I'm pretty sure there's no law or anything saying you have to be a certain age. I think if you're under 18, your parents are generally required to sign a model release. It also depends on where you go, though, because a lot of modeling agencies will refuse to take shots of girls under 18 in bikinis.
Alright, but the girl who asked the question is 13 and to me she is still a child and does not need to be a "bikini model"
Just pick up the phone book or do an internet search for modeling agencies in the city or near where you live. Good luck
Ehh some agencies require the age of 15.. but really depends on where you live
if you are talking like Victoria secret then you will have to be 18 yrs old
My guess is at least 18, but 21 is more acceptable in my book.
i know that this one famouse chik did hers at 16]
