A coffee stop, a meeting, a walk through the city. A relaxed T-shirt can change the feel of a whole outfit. The secret is choosing proportions you enjoy wearing.
What is a boxy T-shirt?
A boxy fit is usually wide with more square proportions. It does not necessarily mean cropped. An oversized fit adds room and can also be long. A T-shirt can be both boxy and oversized, so always check the actual measurements.
Hypster is SEOUL REBEL's boxy T-shirt. Compare its chest width and length with a T-shirt you already love. Choose between the SR monogram and the SEOUL REBEL wordmark for a signature that feels like you.
A closer look at our size L Hypster
Laid flat, the Hypster shows its broad body and dropped shoulders. Our size L sample felt very roomy when tried on.

The maker lists 67 cm across the chest and 68 cm in length for M, and 70 cm by 70 cm for L. Measure pit to pit and from the high point of the shoulder by the collar down to the hem. If a tee you like measures around 67 × 68 cm, start with M.
The 200 gsm Hypster is roomy and lighter. The 280 gsm Asher is roomy too, with a denser jersey. Check each size guide, then choose the fabric weight you prefer.

Should you size up?
Not automatically. An intentionally roomy cut is different from a regular T-shirt bought several sizes larger. Check the length, shoulders and sleeves before choosing more volume. Our pieces are unisex: your preferred shape matters more than a men's or women's label.
Make it your own
Try a boxy T-shirt with straight trousers, or add an open overshirt for another layer. Seoul is the inspiration, but you do not need to follow K-pop or K-dramas to enjoy the look. Keep the styling simple and let the proportions speak.
Are boxy T-shirts always short? No. Compare the length in the size guide.
Is a heavier fabric the same as an oversized fit? No. Fabric affects drape; fit describes the garment's proportions.
Can anyone wear a boxy fit? Yes. Choose the measurements and volume that work for you.
