QVC Sizing

The last couple of things i have ordered were Bass shoes and a bra. Is Qvc getting it’s things from a different supplyer, i bought a bra the size i wear and it was 2 sizes too big and a pAir of Bass shoes taht were way to big, nothing said u beter size down 2 sizes. And then i can’t send them back because u cant return as is products so i’m just stuck with shoes that arent being warn by anyone. will have to think hard about continueing to order from QVC
