Binder vs Spanx

Love Spanx, I get them at a boutique in my city, but the same designer of Spanx has a lower priced brand at Target as mentioned in another post.  Works just as well.  I could not wear them though until 6 weeks out, because of the thigh work I had done, but for my TT they were great,  wore them forever and still do at times.
