Everyone was saying that they went a size bigger since they might shrink in the wash. I am a power lifter and weightlifter so i tend to have larger shoulder and back muscles, usually my bra is a 36 so I went ahead and got a 38. Dont be fooled when you open them, when they were in the package I thought they looked HUGE but they fit great. I haven't washed them yet so i don't know how much they will shrink but the two that i have worn so far are incredibly comfy and fit great. I will totally be buying more in the future.
