Oversized is a cut, not a mistake
There is a difference between an oversized tee and a tee that is simply too big. Oversized is a deliberate cut: a boxy, straight silhouette that hangs from the shoulders instead of hugging the torso. The width and the length are both planned. A regular-fit tee is shaped to follow the body. Both are valid — they are just doing different jobs.
What 240gsm does to the fit
Fabric weight decides whether a boxy tee is a sculpture or a tent. A standard teeshirt (around 150–180gsm) is light and clingy; in an oversized cut it folds into itself and looks sloppy. At 240gsm, the cotton is heavy enough to hold the boxy shape — the drape stays clean, the shoulders keep their line, and the garment reads as intentional. Weight is the hidden half of fit.
The sizing rules that actually work

- True oversized: order your normal size. The cut already does the work — no size-up needed.
- True-to-size look: between sizes, size down. The boxy cut means you lose the “smaller shirt” problem; you just get a closer silhouette.
- Layered looks: if the tee will sit under a hoodie or overshirt, take your normal size or one up, depending on how much drape you want.
- Length check: boxy cuts are usually shorter in the body and wider across — if you are tall, check the garment measurements before ordering.
The TATSU cut
Our tees are oversized boxy, 240gsm, in sizes S–2XL. The fit is the same across the catalog — After Rounds, Ryujin Vanguard, Impact Core, all of them — so once you know your size, you know every tee. We are made to order, and every product page carries a size-chart image with garment measurements. When in doubt between two sizes, that chart settles it faster than any third opinion.
The short version
Regular fit hugs; oversized hangs; boxy is the specific cut that makes oversized look deliberate. If you want the full look, stay true to size. If you want it cleaner, size down. If you want to see the cut for yourself, the whole catalog is here — free US shipping over $75, so the only risk is choosing wrong, twice.
