If I'm sitting in my dorm or whatever, often no. Out in public, 90% of the time. I have large breasts, so it's uncomfortable to go without one. And I have noticed when I do go without one and you can tell, I get odd looks and it annoys me. People don't bother me. Their attitude towards bras do. I hate them, but I'm usually wearing one if I'm out.
I always wear one when going out. Around the apartment I usually wear one of those supportive cami's. I just don't feel comfortable without a bit of support. My gals are needy.
When I was smaller, I often went out without one. Now it hurts to walk any significant distance without one... So, for walking around campus, a bra is a must. So, yeah, I wear one most days, though it generally comes off as soon as I get home!
I've got lil b cuppers and I almost never wear a bra. I wear a sports bra when working out or planting trees, but thats about it. Sometimes my nipples get stared at but, frankly, I don't care.
99% of the time no bra. sometimes I'll wear supportive camis under white shirts, or if I'm going somewhere a little more formal. but as I have smallish breasts I have no need to wear them, and I've read too much about the bad things bras can do to you. also, I personally see nothing wrong witht the shape of my breasts, and if others do, thats their own hangup
I almost never do and almost always do when I'm outside of the house. Today I didn't while I was in the photo lab, but that's mostly in a dark room and I was wearing a fleece vest so no one could notice. I feel awkward without one on, at least where i think it's noticeable that I'm not wearing one.
I have to wear one to be comfortable. I'm just a B but they're an odd shape that...kinda sags to tell you the truth.
I feel more comfortable when I wear a bra so yes, I wear one most of the time. During the day I mean.
I always wear one (except when I'm in my pajamas). Mine are comfy and keep me warm. They aren't the ones with the two cups, wire, and snaps. They're like this: http://www.target.com/gp/detail.htm...454210-6643808?_encoding=UTF8&asin=B000F6WELC
At home, I rarely wear a bra... But outside of the home, I usually wear one of those supportive camis that someone else mentioned. They feel like an undershirt, but have a little support to keep them in place. I have a small D cup, so they need to be under control when not at home. One of my jobs is a dance instructor and in order to keep from bouncing around and putting an eye out, I have to wear two sports bras.
I almost never wear one. I'm big all around, but my boobs are small relative to everything else, so it's hard to find one that fits right anyway... I feel fine without it so I just leave that alone. I always feel so good when I sell my backless tops to large-chested women. Most backless apron tops don't offer any support, but the patternI designed for them years ago works really well. My customers swear by them - I've known so many women who thought they could never wear something like that (because they don't want to go without a bra) until they tried one of these on!
