Aritzia vs COS: which t-shirt wins?
Both land in the mid tier — the Aritzia Aritzia Cotton Jersey Tee at $38, the COS Heavyweight Crew-Neck Tee at $39, just $1 apart. Here's how they stack up, head to head.
| Aritzia | COS | |
|---|---|---|
| Price | $38 | $39 |
| Material | Soft cotton jersey, with some structured cotton-modal blends for a denser, shape-holding feel. | 100% cotton, ~7oz heavyweight structured jersey. |
| Fit | Varies by line from fitted and cropped to relaxed, all with a flattering, considered silhouette. | Boxy and slightly oversized; size down if you want a cleaner fit. Holds a structured silhouette. |
| Quality | Good fabric and a stable knit, with fit being the standout feature. | Above high-street average — thick, opaque cotton that holds shape; consistency varies by batch. |
| Best for | Fashion-forward everyday wear with a flattering silhouette. | Minimal, design-led outfits and anyone who wants a heavyweight boxy tee that holds its shape. |
| Care | Machine wash cold on gentle and lay flat to dry to maintain the fit. | Cold wash and hang dry to keep the structured, boxy hand from softening out. |
Aritzia's Cotton Jersey Tee is $38 and built around fit; the COS Heavyweight Crew-Neck is $39 for a genuinely heavyweight ~7oz, 100% cotton tee. The dollar gap is meaningless here; the real difference is a flattering jersey cut versus thick, opaque, shape-holding cotton.

Which should you buy?
At a buck apart, buy on feel and silhouette. Get the COS if you want a substantial, opaque heavyweight tee with a boxy structured drape, and you don't mind that fit consistency varies batch to batch. Get the Aritzia if a flattering, reliable fit and softer jersey matter more than fabric heft. The COS rewards a heavyweight preference; the Aritzia rewards a fit preference.
