Balenciaga check shirt (inner down quilting material)! I purchased it at Balenciaga in Kobe Motomachi Daimaru for 178,200 yen! Size 39 (I'm listing it as M since I don't know what size 39 is), but I think it could fit S, M, or L depending on your body type! It's oversized, so I think it can be worn by people of various body types. The inside is quilted, but it's not thick, so I think it can be used widely from winter to spring and autumn! I am 168 cm tall and weigh 63 kg, and I wore it oversized! The other items I have listed generally match well, so please take a look if you'd like (^^) If you would like an authenticity check, please let me know and I will change it in the editing.
