What you should say is a U-shoulder bra. This is a style of underwear. Just like clothes are divided into short skirts and long skirts.

Bras with U-shaped shoulder straps are more docile, and the shoulder straps are not easy to slide down, so they are suitable for wearing shirts, professional clothes and other foreign clothes without backs.

Some bra straps are designed to be wider, which is related to cups. The shoulder straps and straps on both sides need to be designed in a certain shape, so as to achieve a better breast gathering effect, expose beautiful cleavage and make the breasts look firmer.
