Nijisanji Sango Chuo Cosplay Costume (Standard) Vendor: Amazon (Size L) Although it's from Amazon, I wasn't happy with the original knee-highs, undershirt, and cardigan, so I'm using commercially available ones. Also, the ribbon has double-sided tape inside to make it look better and wider. Knee-highs: Assist Black undershirt: Amazon, Size LL Cardigan: WEGO, Size L Instant purchase ○
