They run alittle small. It was cute tho for my cowgirl party!❤️The size S/M/L seems more only for the breast circumference and nothing to do with the cup size. More idea for women who have smaller breast like a A or B cup. The bra overall is beautiful and comes exactly as shown in the picture.Wore it to a music festival! Felt amazing ??I did really like this bra. I got a lot of compliments. Its sorta pointy feeling make sure to go a size up. I originally ordered a small/med. Very tight runs more on the small size then the Med. The Med/large fit well. I wear a 36B.I'm a 38D. My boobs do not fit in this thing. It's really pretty though ?Sizing is slightly small, but not too bad. If you are unsure on sizing, size up. This is a really pretty piece for the price.The bra fits a little small but it went perfect with my Birthday Dress. Everyone thought that it came with my dressWas exactly what I wanted. Quality was great too. Would definitely order in other colors.
