I, as a small chested person, feel the need to put my two cents in. I've found that few people are happy with their bosoms, but pleeaaseee dont think that all small chested girls want really big bosoms!
And, yes, you should really try to get properly fitted (probably by someone close to you than going to Victoria's Secret.. cause I dont think they're any more accurate than anyone else, and it's just more awkward, and they do it above your clothes when you probably should be in the nude...)
I hope this helps you guys some!
