I'm one week away from 7 months - up until this point I've been able to successfully wear clothes that I had when I wasn't pregnant with a belly band from target, that thing worked great. Now that everything is starting to get much larger and my hips are spreading, it's not working.... I literally have no clothes that fit me and I just want to cry about it because maternity clothes are way too damn expensive.
Try your local thrift shop. I had great luck there, plus I wear a ton of leggings.
