A C cup is actually quite large for a band size of 30. 30 is a little small, but you sound like you have a perfectly good body. :)
It's a pretty small size but hey that's fine! I measure as the sister size of 30C, which is 28D. Think of it this way: a 30C has the exact same volume as a 32B and 34A. Victoria's Secret actually have pretty inaccurate sizing methods, though. If you are that skinny, I would bet that you are around a 28D. You should measure yourself to get the most accurate measurement using this calculator:
your 95 pounds so its large for your body size but its looks good.a 36c is bigger than a 30c.a 30c isn't huge but its a little bigger than average for your body size. heres a woman with a 30c and she looks kinda busty
Sure it's fine it's not to big and not to small I'm 13 and 5'7 and 130 pounds and I'm a 36c so your good
