This character is often shown wearing a bra.
A brassiere is a woman's undergarment that supports her breasts. Bras are typically form-fitting and perform a variety of functions and have also evolved into a fashion item. The primary purpose of a bra is to enhance the wearer's comfort by supporting her breasts.
Do not use this trait related to sex scenes where a character's undergarment is briefly shown. Use it on occasions where characters are displaying their undergarments occasionally either because their other clothing are designed in a way that it reveals them or when they don't wear anything else to cover their undergarments.
