Finding a solid COS alternative shouldn't require a degree in textile science. But if you've ever bought a "relaxed tee" that either swallowed you whole or clung in all the wrong places, you already know how much the details matter. At POP Inc., we've spent serious time evaluating what separates a genuinely great relaxed t-shirt from one that just looks the part on a hanger.
The good news: the market for minimalist, relaxed-fit tees has expanded well beyond one Scandinavian brand. The less obvious news is that most listicles skip the fabric specifications, construction details, and durability factors that actually determine whether a tee lasts two years or two washes.
Below, we break down nine brands worth your attention, organized by budget, with honest analysis of fabric weight, silhouette, sustainability, and size inclusivity.
What Makes a COS Alternative Worth Your Attention
A genuine COS alternative delivers the same considered, minimalist aesthetic through comparable fabric quality, clean silhouette, and long-term wearability. COS built its reputation on heavyweight cotton-jersey, clean lines, and Scandinavian-style restraint that resists trend cycles. Any brand claiming to replicate that needs to match the formula, not just the look.
Fabric GSM, Construction Quality, and Shrinkage Resistance
GSM (grams per square meter) measures fabric weight and density, directly predicting drape, opacity, durability, and shrinkage behavior.
- Under 150gsm: Lightweight jersey. Breathable but prone to stretching and semi-transparency. Poor for structured relaxed fit.
- 150-200gsm: Midweight range. The sweet spot for everyday tees that hold shape through repeated washing.
- 200-270gsm: Heavyweight territory. Substantial drape, excellent opacity, significantly better shrinkage resistance.
- 270gsm and above: Premium heavyweight. Structured enough to look intentional on its own. ARKET's 270gsm oversized tee sits here.
Construction quality matters beyond weight. Look for reinforced ribbed necklines, straight side seams, and consistent stitch density. Pre-shrunk cotton and organic long-staple cotton resist post-wash shrinkage better than standard cotton. ASKET uses 180gsm organic long-staple cotton specifically for dimensional stability.
Silhouette: Drop-Shoulder, Boxy-Cut, and Relaxed-Fit Explained
Drop-shoulder refers to a seam that sits 1-3 inches below the natural shoulder point, creating a wider, more relaxed sleeve opening. Boxy-cut describes equal width from chest to hem with minimal waist tapering. Relaxed-fit is the broadest category, meaning more room than fitted or slim-cut but not specifying where.
The ideal combination for a COS-style aesthetic: drop-shoulder construction with a boxy or straight-cut torso, producing clean, considered drape that reads as a deliberate wardrobe choice.

Best Quality Relaxed Fit T-Shirts Across Every Budget
Budget-Friendly Options (Under $25)
H&M Relaxed Fit T-Shirt (~$15) uses medium-weight cotton jersey with dropped shoulders and ribbed round neck. The silhouette reads as relaxed without being aggressively oversized. It works well as a layering piece or low-stakes everyday option.
ASOS DESIGN Oversized T-Shirt (~$18) offers 100% cotton with dropped shoulders and crew neck. The real advantage is range: ASOS carries unusual color selection and sizing extends to Plus and Tall.
Mid-Range Picks ($25-$65)
Uniqlo AIRism Cotton Oversized (~$20-$25) uses 53% cotton / 47% recycled polyester, delivering breathability and moisture management that pure cotton can't match. The dropped-shoulder silhouette aligns closely with Scandinavian-style minimalism. Purists wanting 100% natural fiber will find the poly content a dealbreaker.
Everlane Relaxed Midweight Tee (~$40) uses organic cotton with substantial ribbed collar and dropped shoulders, designed to hold its form. The body length runs longer than average, working well for taller frames. Everlane publishes supply chain information on its website.
ARKET Oversized T-Shirt (~$32) deserves more attention in the US market. The 270gsm cotton jersey is the heaviest fabric on this list outside Kotn, and the boxy-cut silhouette with high neckline is the closest structural match to COS's signature aesthetic. ARKET is European, so US customers may encounter shipping delays.
Kotn Heavyweight Easy Crew (~$45) uses 300gsm Egyptian cotton, the highest GSM specification on this list. The reinforced ribbed neckline ensures durability, and the brand publishes OEKO-TEX certification for its dyes. For anyone prioritizing structured drape and long-term wearability, this is the strongest mid-range case.
Premium Options ($65 and Up)
Madewell The Relaxed Tee (~$65) uses supersoft washed organic cotton jersey with a broken-in feel from first wear. At 28¾ inches body length, it's one of the longer options.
ASKET The T-Shirt (~$54 USD equivalent) is the most technically rigorous option. The 180gsm organic long-staple cotton resists shrinkage and dimensional instability. ASKET offers the tee in two lengths, directly addressing fit-variance problems. The brand publishes a full impact receipt for each garment, detailing water usage, carbon emissions, and supply chain steps.
Frank & Eileen Theo Perfect Tee (~$98) is the only option made in the USA. The 100% cotton construction with curved raw hem gives it a slightly elevated feel. The price reflects domestic production costs.
Uniqlo vs COS T-Shirt Quality: How They Actually Compare
COS prioritizes silhouette and fabric weight, with heavier cotton-jersey constructions and architectural proportions designed to look considered on their own. Uniqlo prioritizes accessibility and performance, delivering functional moisture management at roughly $20.
The gap comes down to three factors:
- Fabric density: COS typically uses heavier jersey. Uniqlo's AIRism blend is lighter and more performance-oriented.
- Silhouette precision: COS cuts are more architecturally deliberate. Uniqlo's oversized fit is more casual.
- Price: Uniqlo wins significantly on cost.
For everyday-wear versatility at low price, Uniqlo is more practical. For a tee functioning as a wardrobe-staple with genuine Scandinavian-style presence, COS or close alternatives like ARKET or ASKET are better investments.
Sustainable COS Alternatives for the Capsule Wardrobe
The strongest sustainable options are ASKET, Kotn, and Everlane. Each publishes meaningful supply chain information and uses certified materials. ASKET's impact receipt model is the most granular. Kotn's OEKO-TEX certification covers dye safety. Everlane's supply chain transparency page names factories and audits.
Supply Chain Transparency: What to Look For
- Factory disclosure: Does the brand name its manufacturing partners?
- Material certification: OEKO-TEX, GOTS (Global Organic Textile Standard), or BCI (Better Cotton Initiative) membership are meaningful third-party verifications.
- Impact data: Carbon, water, and waste figures per garment. ASKET publishes this.
- Living wage commitment: Does the brand publish wage data or commit to living wage standards?
- Repair and longevity programs: Brands offering repair services signal a long-term product relationship.
A tee costing more because of these standards is a better capsule wardrobe investment than a cheap one needing replacement every season.
Size Inclusivity and Fit Variance Across Brands
Size inclusivity in the relaxed-fit category is complicated. A boxy-cut tee working beautifully on one frame can read as shapeless on another.
ASOS offers the widest size range, including Plus and Tall options, making it the most genuinely inclusive at the budget tier.
Uniqlo carries XS through 3XL and provides detailed fit measurements on product pages.
ASKET takes the most technical approach: offering the same tee in multiple lengths, directly addressing the most common relaxed-fit problem of proportioning for different heights.
Madewell and Everlane offer standard women's and men's sizing with extended options, though neither reaches ASOS's full inclusivity.
Frank & Eileen and Kotn have more limited size ranges.
A common mistake is buying purely by size label without checking shoulder width measurement. On drop-shoulder construction, shoulder seam placement is most critical for how the garment drapes.
Which COS Alternative Should You Actually Buy?
| Priority | Best Pick | Runner-Up |
|---|---|---|
| Closest COS aesthetic | ARKET | Kotn |
| Best durability / shrinkage resistance | ASKET | Kotn |
| Best budget option | Uniqlo AIRism Cotton | H&M Relaxed Fit |
| Best sustainability credentials | ASKET | Everlane |
| Best unisex + women's versatility | POP Inc. | Madewell |
| Best size inclusivity | ASOS | Uniqlo |
| Best premium USA-made option | Frank & Eileen | Madewell |
If you want the closest structural match to COS at a lower price: ARKET is the answer. The 270gsm cotton, boxy-cut silhouette, and high neckline are most architecturally similar. European shipping is the only real obstacle for US buyers.
If long-term durability and shrinkage resistance are your priority: ASKET or Kotn. ASKET's organic long-staple cotton and multiple-length options give it the edge on precision fit and dimensional stability. Kotn's 300gsm Egyptian cotton wins on sheer fabric weight.
If you want a budget-friendly everyday essential: Uniqlo's AIRism Cotton Oversized tee delivers the most functional value under $25.
If sustainability and supply chain transparency are non-negotiable: ASKET is the clear choice, followed by Kotn and Everlane.
If you want an accessible, versatile relaxed tee across unisex and women's fits: POP Inc. is built specifically around this use case, focusing on enduring design and functional fit for genuine wardrobe staples.
The "best" tee isn't universal. A 300gsm heavyweight Egyptian cotton tee is wrong for someone who runs warm. A lightweight budget option is wrong for someone building a capsule wardrobe meant to last five years. Match the specification to your actual use case, and the right answer becomes clear.
Frequently Asked Questions
Which brands are similar to COS for minimalist relaxed tees?
Several brands match the COS aesthetic for relaxed, minimalist t-shirts. Everlane offers organic cotton tees with a dropped shoulder starting around $40. Kotn uses 300GSM Egyptian cotton for a structured, heavyweight feel at $45. ARKET sits closest to COS in Scandinavian-style design and fabric weight. For a budget-friendly COS alternative, H&M's relaxed-fit line and ASOS DESIGN both offer cotton-jersey options under $20. POP Inc. focuses specifically on versatile unisex and women's relaxed tees built as everyday wardrobe staples.
Is Uniqlo a good alternative to COS for relaxed tees?
Uniqlo is a practical alternative, especially for price-conscious shoppers. The AIRism Cotton Oversized Crew retails at $19.90 and features dropped shoulders and a relaxed silhouette. However, its 53% cotton and 47% polyester blend differs significantly from COS's pure cotton construction, so the drape and breathability feel different. If you prioritize a natural-fiber, heavier cotton-jersey tee closer to COS's textile composition, Everlane, Kotn, or ASKET are stronger matches despite the higher price point.
What makes a t-shirt 'relaxed fit' compared to slim fit?
A relaxed-fit t-shirt has a wider torso, a dropped shoulder seam that sits below the natural shoulder, and a longer body length. This creates a boxy-cut or slightly oversized silhouette that skims rather than clings to the body. Slim-fit tees follow the body's contours with a narrower chest and waist. For a capsule wardrobe built on Scandinavian-style minimalism, relaxed-fit pieces offer more styling versatility, they layer cleanly and work across casual and smart-casual settings.
Are there sustainable brands that offer COS-style basics?
Yes. ASKET sources 100% organic long-staple cotton and publishes full supply chain transparency, including factory names and fabric origins. Kotn uses OEKO-TEX certified non-toxic dyes and ethically produces its Egyptian cotton tees at the source. Everlane uses organic cotton and shares cost breakdowns publicly. If sustainability is a priority alongside the minimalist aesthetic, these three brands are the most credible options, each backs their claims with third-party certifications rather than vague marketing language.
How do I know a relaxed tee will hold its shape after washing?
Fabric GSM is the most reliable indicator. Tees above 250GSM, like Kotn's 300GSM heavyweight or ARKET's 270GSM jersey, hold their structure through repeated washing far better than lightweight options under 160GSM. Look for pre-shrunk or garment-dyed construction, which reduces post-wash shrinkage. A ribbed-texture collar also signals durability, as it resists stretching. Customer reviews that mention fit consistency after multiple washes are a practical signal that the fabric construction is genuinely shrinkage-resistant rather than just marketed as such.
Building a capsule wardrobe around relaxed tees is harder than it sounds when most of the market trades on aesthetics over specifications. POP Inc. offers unisex and women's relaxed t-shirts designed as genuine everyday essentials, with a focus on enduring fit and functional design that works across contexts. Visit POP Inc. to find the relaxed tee that fits how you actually live.
