Now bra has become a garment with erotic significance and a feminine symbol with political and cultural significance beyond its primary function. Women choose to wear bra because it make them feel good, more supported, and more under control.
Bra designers and manufacturers originally produced bras that were purely functional and gradually added elements to improve the design, but they have now largely shifted from functionality to fashion. At the same time, it is very important to wear a bar made of right fabric, some people are allergic to some fabric type, so cotton should be the choice, it let the air pass though and lot make you sweat in that area.

Therefore a bra should not be so tight. Some bra come with a metal wire, just imagine when a underwire bra set off the metal detector at an airport.
