/cgl/ - Cosplay & EGL

My Lief "Assorted Tea Set Series" OP order in Navy just arrived and I don't know what I was on when I was looking at promo photos, because I could have sworn that the vertical stripe was white.

It's just arrived, and obviously, it's this weird muted mint colour that I apparently wished away when I was scrolling through the promos... but it means that all my blouses, which have a warmer ivory undertone to them, look awful with it.

I got the puff sleeve OP, and it also gives me hella loafboob because it's a little too big. Any advice on how to coord to stop it making me look massively top heavy? Any advice on colour picking?
