It's amazing how most of us here "enjoy" the sensation of being supported and contained while most women do not. After talking to my fitter about it, she says it's because we take the time to be properly fitted. A lot of women either won't take the time or won't listen to the fitter. They were measured years ago and they know what size they are. They don't need to be fitted again. My fitter says she becomes so frustrated with some of her customers because they won't listen. She can see the problem but the client won't accept it.
Personally, I get fitted once a year. Sometimes my size has changed. Sometimes it hasn't. My fitter says that's why I enjoy wearing a bra. It's comfortable and it's doing what it's designed to do. And that's the way it should be for everyone. Most women are uncomfortable in their bras and the bra can't do its job correctly because of it.
Bras are such a personal thing that no two people wear a bra the same way.
