Mandee, I usually wear the ones with the clasp in the front and not the back. That probably makes the difference. The metal is all in the clasp and not so much the underwire in the cup. Okay I just told the guys too much information.
Ahhh! Okay, yep that's probably it. I only wear the back clasp ones because one of my first bras as a young girl was a front-hook one and I remember one time I was wearing it in like 4th grade and I was sitting in class and I guess I accidentally smooshed my boobs with my arms when I was doing something, and the bra came undone and I had to rush to the bathroom and hope that no one could see what had happend. Since then, I refuse to wear them.
I had bigger boobs than everyone else until about freshman year... now they are just normal.
Also... I was the tallest student in my kindergarten class. I looked like a first grader. lol.
