Great, safe staple
I have ordered from LuLu's before so I went with a small (5'8, 160, 34D) and it fit perfectly. It buttons nicely without being snug and when I let it hang open it falls exactly like pictured--not splayed out. I can certainly feel some tension just across the back between my shoulders. And had this been a full blazer with sleeves then it may have been too tight. But because it doesn't have sleeves it fits perfectly.
