Better circulation - bras can impede blood flow to back and chest muscles, contributing to sore back muscles.

Increase comfort - Dr. Lucky Sekhon, a New York based Obstetrician, says that women who are used to wearing a bra may initially feel conscious and exposed when they go braless. But as women go braless more often, they feel more comfortable and free.

Better breast skin health - women who wear bras often experience boob sweat, clogged pores, skin irritation, and body odor. Dome women even developed acne mechanica caused by bra straps.

Improved shape - Dr. Sekhon that women with breasts of all sizes can benefit from bralessness. "Women with larger breasts may initially feel more uncomfortable than those with smaller breasts as their muscles may initially be weak and not feel strong enough to provide adequate support", she says. "Over time, though, their bodies will adjust and naturally start to support the breast tissue appropriately, without the aid of a bra." She states that there is evidence "that wearing a bra can make the muscles and ligaments that support the breasts lazy overtime, leading to breast sagging and laxity." She says the belief that going braless for an extended period of time makes your breast sag is a common misconception. "Women who have gone long periods without wearing a bra often report that this leads their breasts to being firmer, rounder, and perkier over time", she says. Women with larger or fuller breasts may feel more back strain when not wearing a bra, though. "It can take weeks to months to build up the strength in their chest and back muscles for the breast to become well supported without a bra.
