Hanes Women's Originals Seamless Bralette, Rib Contour Bralette, ComfortFlex Fit

Comfortable and fits perfectly

I bought 2 of these in extra small, I am 5ft 5 inches, 120 pounds with 32a breast size and it didn't fit. I gave to my mother who is a 34a breast size and they fit comfortably on her, but for me they were too big.
