Size Guide (Classic T-Shirt)

— A garment that will be a long-time part of your daily life —

The Classic T-Shirt is made from 190g/m² heavy cotton. It features a moderate thickness and a sturdy, non-sheer silhouette. We use ring-spun cotton for the yarn. The fibers are fine and supple, and the fabric will become more comfortable against your skin with each wear. It is also resistant to losing its shape after repeated washings, making it a piece you can cherish for a long time.

Sizes are available in unisex (for both men and women). Details are as follows:

S: Length 66 / Width 49 / Sleeve Length 19
M: Length 70 / Width 52 / Sleeve Length 20
L: Length 74 / Width 55 / Sleeve Length 22
XL: Length 78 / Width 58 / Sleeve Length 24
