I got a size large, I have a 34DDD chest. It's a little tight around my boobs but not bad! It's like a crop top though not a full length shirt which I wasn't expecting BUT it's still cute though & it's super soft!
It's been a while since I ordered this shirt and I love it so much. I wear it so often. The only thing I could complain about is the fact that it fades quite quickly (but it looks cool) and it wrinkles easily. I would recommend hand washing it with something gentle and hanging it up to air dry. Other than that it's one of my best purchases clothing wise.
