My are horrible! I'm 13. They are a 34 B but i have a very skinny frame and they look absolutely mive on me. I hate them so much that i went on a dangerous diet and lost one stone and a half cuz i was quite chubby, my didn't decrease in size. Puting on weight isn't an option and neither is surgery. (trust me it woul be if i had a choice). Someone help e make them smaller please!!!????
