I originally got a busty-medium because I was on the line between that and th busty-small. After getting it and wearing it for a few days, it was as clear I should have gone with the smaller size. I contacted. The seller and they have been great to work with and were quick to send the new size and replace the other even though it didn't have tags. They were awesome and this bra is great for sleeping or just kicking around the house. I have been very happy with it and would recommend it to others. For reference, I am a 32DDD/F and prefer the fit of the small-busty.
