The size chart put me in a size large, but I saw so many recommendations to size up in the Facebook group that I ordered an XL. For me that turned out to be a mistake. The back/non wrap side was far wider than my body and so stuck out, particularly under the arms, and I wasn’t able to wrap it tightly enough to feel secure. I ended up swapping my XL for a medium on the bst and the fit is much better. I do miss the longer ties and bit of extra boob coverage that I got from the xl, but the medium is by far the better fit. The material feels really good and the suit is incredibly flattering to my hourglass figure. I’ve never felt so body confident in a two piece swimsuit. Some of the tying style variations don’t feel very comfortable, and I think I’ll probably go for the wrap-style the majority of the time.
