Is it possible that my boobs are bigger than my older sister?

I have a really big problem. My sister is 17 and I'm 15 and I have a bigger bra size. Is that normal?

Yes, that's possible. Everybody is an individual. My kids are both very different, so it's natural you & your sister are as well.

It is ABSOLUTELY normal. I have a chick friend who has bigger breasts then her sister and her sister is 2 years older (she is 15 her sister 17) what a coincidence...

I'm fifteen and my sister is twenty six and I'm way bigger.
its definitely possible

yeah it is normal I have bigger breast then my mom and she is 37 and I am 13!

LMAO are you serious stephani?!

Just because your sisters doesnt mean your both going to have the same bra size. We are all individuals who inherit different genes. Even though you both have the same parents!!

Heredity has more than anything else to do with the size of your breasts. Just remember that you get genes from both sides of your family. Maybe the women on your father's side of the family tend to have big breasts and the women on your mother's side tend to have smaller ones, or vice versa. You take after one side of your family, your sister takes after the other.
