I bought one of these about a year and a half ago when I was new to he bralette scene and trying out different styles. It swiftly became my favorite! I am a 34 A/B and ordered a Med back then (reviews stated it ran quite small). It fit PERFECTLY.Gap put these bralettes on sale in July and I order...ed 3 more in a Medium. I didn't even think to read the reviews as I thought I was ordering exactly what I already owned. Wish I had - they changed the sizing of these bralettes. They are slightly bigger around the rib cage, but a lot bigger in the chest area than they used to be. Too much fabric and they rise up too high on my chest. (If I was a 34 C/D, I think these would fit better.) Thinking maybe a Small would fit better, I drove an hour to the closest Gap and tried on the Small. The chest area fit much better, but the band around my ribs felt too constrictive, so I kept the Medium and tried to shrink them a bit in the dryer. They did shrink some, but there is still excess fabric around my breasts and it comes up too high on my chest and I can't wear some of my v-neck shirts with them. The band around my ribs shrank to almost perfect size though, so I still wear them, but feel a tinge of disappointment every time that they aren't "just right". (In hindsight I do wish I had exchanged them for the Small.)Extraordinarily comfortable, but if you've owned these in the past, beware of the new sizing when ordering new ones!!
