Ana!! I'm 42, but I have to say I've fallen in love (again) with thrift store shopping. I did this in high school and college. After kids, it became a pain. There's a local resale shop here called Uptown Chic or something like that and they have the cutest clothes that are lasting me a long time.
I've also gotten clothes from my local Buy Nothing Facebook groups and someday I'll attend a clothing swap, which are quite popular here in Tulsa! :D
