The ASASI Fit Guide: Classic, Relaxed and Oversized, Explained
ASASI runs three distinct silhouettes across its shirts and t-shirts, and picking the wrong one is the most common reason a piece doesn't get worn as much as it should. Here's the difference.
Classic Fit
The closest to a traditional cut, Classic fit follows the body without sitting tight against it. The Vāyu t-shirt is ASASI's clearest example — a relaxed silhouette that drapes rather than clings, sized true to what's on the label. If you're unsure where to start, Classic is the safest first purchase.
Relaxed Fit
A step looser through the body and shoulders, Relaxed fit shows up across most of the Origin shirt line. It's built to be worn open over a tee or buttoned on its own, with enough room to move without reading as oversized. This is the fit most ASASI customers settle into for everyday wear in Bali's heat, since the extra room helps air move rather than trapping it.
Oversized Fit
The Kavash t-shirt and the Affine short-sleeve shirts both run genuinely oversized — dropped shoulders, more room through the body, designed to be worn exactly as cut rather than fitted down. Size down on oversized pieces if you're between sizes and want a cleaner line; size true if you want the fuller silhouette the cut is designed for.
A Simple Rule
If a product description mentions "wears like a size up" or "oversized silhouette," it's telling you the cut is intentionally loose. Everywhere else, ASASI sizing runs true, and the model measurements listed on every product page are there specifically so you can compare against your own build before you order.
Still unsure between two sizes? Any of ASASI's four Bali stores can fit you in person, and the team can talk you through which cut suits how you actually plan to wear it.
Why ASASI Runs Three Fits Instead of One
A lot of menswear brands standardise on a single silhouette across the range, which simplifies production but assumes every piece is worn the same way. ASASI's climate-first approach means a linen shirt worn tucked for dinner and a t-shirt worn loose on a beach day need genuinely different cuts to work properly, not just different fabric. Running three fits is more complex to produce but means each piece is actually built for how it's likely to be worn.
Reading a Product Page for Fit Clues
Every ASASI product description includes the model's height and the size they're wearing, which is there specifically so you can compare against your own build. A model listed at 178cm wearing a size M in an oversized piece will look noticeably different on someone considerably taller wearing the same size — the proportions of an oversized cut shift more dramatically with height than a fitted piece does. If you're taller than most of ASASI's models, sizing up on Relaxed and Oversized pieces is usually the safer call.
How the Fits Compare Side by Side
Classic fit, seen in the Vāyu t-shirt, sits close enough to the body to read as a normal, well-cut tee rather than making a statement about fit at all — it's the fit to default to if you're not deliberately going for a look. Relaxed fit, across most of the Origin line, adds room through the chest and sleeve without losing shape, which is what lets a Relaxed shirt go from buttoned and tucked to worn open over a tee without looking wrong either way. Oversized, in the Kavash and Affine short-sleeve pieces, commits fully to a boxier silhouette and dropped shoulder, and works best when the rest of the outfit is kept simple rather than competing for attention.
Common Fit Mistakes
The most common issue staff see isn't buying the wrong size, it's buying the wrong fit for the intended use — someone wanting a sharp, put-together look for dinner picking an Oversized piece because it's the newest release, or someone wanting an easy beach t-shirt picking Classic fit and finding it a touch too fitted for lounging. Matching the fit to the occasion first, then picking the size within that fit, avoids most of the returns ASASI sees on first-time online orders.
Stay understated.
