Excellent but SIZE DOWN
Size: 36E, Color: Black
These bras are the best. Incredibly comfortable and an excellent price. However the sizing is way off. Im usually a 36G or even 36H in other brands. In this brand and style im 36E. Take note to size way down on the cups. Otherwise these are my fave new everyday bra for extra large, heavy-duty cans!
