My bras are getting quite uncomfortable because I think I'm wider now. I figure I should just go get a couple maternity bras since my current ones are underwire. I am very small chested so I only need limited support. I'm guessing about a 36 B would be good for where I am now. I want something that makes my BBs look round and normally shaped, something which will last at least 6 months, and is very inexpensive. Since I'm from the US, I don't know where to start looking. Any suggestions? Give me an idea on prices too b/c we don't have much money. I'll be back in the US in April and can buy them for much cheaper there. Thanks.
