My friend used something from the Motherhood Maternity store and she only got the belly line. BUT I agree with PP, I've heard that it doesn't matter what you put on them, you'll either get them or you won't. I was lucky enough to get them growing up as a chubby kid, so I am bracing myself for whats to come.
