I'm really lucky, I look at the thrift stores all the time and totally luck out for maternity clothes.
All brand names, and always under $6!
I think that's the wonderful thing about maternity clothes, everyone eventually stops having children, and stops wearing the clothes so they have to go somewhere! :)
Last week I picked up this wonderful sundress, I've never been overly pregnant during the summer so it will be nice to be able to wear flowy light things!
My biggest struggle is finding things in my size, I need a Small or XSmall (petite in length is a bonus!) but it always seems like everything is Large - XXLarge.
