Pretty much anywhere that sells underwear sells shapewear too. Amazon, Walmart, Target, Macy's etc. At least for stomach/thighs. Arms might be a bit more tricky.
I found many many places just by doing a Google search for compression clothes . I've also had really good luck Going to St Vincent de Paul Thrift Store And buying What people have donated .
