This is one of those outfits that makes me feel incredible. It's seriously magical, especially if you're an apple shape. I always put on a tight, mock neck white tee under the gray shirt. So adorable. No blazer needed. You won't want one. Both the top and pants are made from the same material. It's thick/substantial but has stretch. I tried pointing out a flaw I saw. there's this tiny little snag(literally the size of a dot) on the top. I think it can be shaved off with a razor. or just ignored. it's very hard to see/notice. both the top and pants are size 2. Gently worn with lots of life left. I LOVE this set. you will not regret it.
