This is a gingham check blouse from GU. Size is M. Width: 51cm Length: 60cm V-neck, sleeveless, and looks neat. Made of 100% cotton, so it's cool to wear even in summer. Since it's sleeveless, the sleeves of outerwear won't bunch up. The neckline looks slightly yellowed (foundation?), but it's only noticeable if you look closely. How about it for the coming hot season?
