Small boobs need support too especially if you are going up and down steps a lot and any physical activity including just walking. Also a bra is needed when you have tender breasts from period and pms. And of course for the nipple reason lol and a white shirt omg! All girls like padded bras and push up bras too!
not all of them do but I imagine the ones that do, do so because they still have SOMETHING there to support and because a bra puts an extra layer between you and your clothes so if you get cold(if ya know what I mean)the whole world doesn't have to know.
*Small breasted girls have nipples too.
*It's a right of passage so many people like to make a big deal out of. Especially at the "first bra" age. A lot of people (girls and guys) WILL tease you if you don't wear a bra regularly.
*They make your bust appear half an inch larger.
Take it from a very small breasted woman, It sometimes looks gross, and I wear a padded bra because I want to look like a woman and not a boy. I am very self conscious about it. When the first time my boyfriend and I slept together ( on the 7th, we will be together for 12 yrs.) I asked him if he was disappointed about me being small breasted, he said "No" It doesn't make me any less of a woman in his eyes.
You know, I ask myself the same question, because I know people who have small chests, but they do need support, we all do, unless you have absolutely nothing there. Don't say they don't need support for their breasts, you don't know that.
