COS Oversized Tailored Shirt

I love this shirt so much but realize it looks too big on me, can’t style it. Couldn’t return because I already cut tags 😭 Size US 8/EUR 38 so suitable for someone who’s in between M-L size. Length 28.5 inches from shoulder to bottom hem. Width 22 inches. Arm 25 inches Never worn outside not even once. Never washed. Bought this from COS directly (paid USD conversion plus duties) because Lydia Tomlinson on Instagram wore it so many times (attached pictures of her outfits). Color is exactly like her pictures. My lighting at home is yellow-ish so color might not be accurate, but I’ve taken both regular pic and flash pic along with video. The color is beautiful suitable to any skin tones, perfect for spring outfits. 100% cotton. The cotton material of this shirt is something I’ve never felt before. It’s like thin poplin, super high quality, doesn’t crease easily at all, very low maintenance in terms of need to steam/iron. It’s very rare to have a cotton shirt that “straighten itself” basically. Price negotiable. Only accept reasonable offers because this is brand new.
