Ok, I read so many reviews and so many said to size up because it runs small. I had doubts but there were so many reviews saying this, so I got a small instead of my usual XS…. Bad idea. I was swimming in this dress. I am an A32, size 0-1 (24-25) in jeans, and the small was hanging off me. I loved the dress enough to get it altered, but it was money I didn’t want to spend. Should have went with my gut feeling and got the XS. It is definitely true to size, the small even seemed a little big for a small. Unless you are gifted up top, it will be a bit big in my opinion.
