I normally wear a medium (32B/C bra) and ordered a S/M! It's kinda hard to find the perfect placement for the back panels on the shoulder area. But once you get that, it's great! Super comfy and airy. It feels like swimsuit material which surprised me. The tassels aren't the same as the picture but no body is really checking out your tassels! The only problem I kinda have is that it's pretty short. Would recommend!
