I purchased COS online for the first time. I tried it on at home, but I didn't know the sizing of COS, and the bust area was a little tight, so I'm putting it up for sale ☺︎ The silhouette is very beautiful, as shown in the photos! (It's also sold on ZOZO, and it says that size 36 is equivalent to a size M. If you want to wear it buttoned up, I think it's made a little slimmer from the bust to the waist.) Single-button tailored peplum blazer, sophisticated black design. Retail price: ¥29,000 - Brand: COS - Color: Black - Style: Tailored peplum blazer - Design: Single button - Silhouette: Peplum silhouette Thank you for looking.
