Okay so I need to buy maternity clothes already but i've been just looking around for good deals. I seen old navy has some nice things on the sale page online. I just don't know how those sizes work? Pre baby I was a size 13 in jeans and large or extra large in shirts I shop in the juniors section. Lol Well I bought some maternity pants at target and they are a medium they fit a little tight around my butt but I like the way they fit. As I get bigger will I need to get a bigger size? As for shirts should I get a large or extra large? or how does that work? Sorry these questions may sound stupid but I'm shopping online so I can't try them on. Thanks for your help this is the first pregnancy I've had to wear maternity clothes.
