What kind of bra does the average teen girl/young woman use?

I am 18, I am also a 30 C. I like underwired, padded bras, that push up. I think that they make me more comfortable because my get hard very frequently, and I hate to think that people can see my through my shirt. I do not think there is any certain kind of bra that everyone should be wearing, I think it just depends on what you like, and what makes you feel comfortable with your body. Your not late just because you like wearing a normal bra, it's just what you like, you do not need to compare yourself to anyone else, because everyone is different. So just wear what you like because no one really compares their bras to others, and no one should look down at you for not wearing padded push up bras, unless they have some issues.
