Customer Reviews (4.8 / 5 · 4 reviews)

Mia ★★★★★

Fits true to the size chart—I’m 160cm and the S sits loose but comfy, perfect for lounging.

Hannah Z. ★★★★★

The 100% polyester fabric is super soft and breathable, perfect for lounging around the house. The 102 cm bust measurement gives me plenty of room to move without feeling baggy.

Ellie ★★★★★

The back length of 82 cm hits just right for lounging around, and the sleeve width gives enough room to move without feeling baggy. Wore it for a cozy game night and it stayed comfortable the whole time.
