I already had this in beige, so I knew I'd like it. It gives you a smooth line under all your dresses and skirts. I ordered a 36B, and it's a perfect fit for me.  I'm 5'2", around 120, and I just step into it and go - very easy to pull on.  I love the gusset to keep it from riding up.  I have a couple of others without that, and I'm fighting them all day, pulling down on them.  When I wear this one out, I'll probably reorder the same one, which is unusual for me - usually there's something newer and better.  I like the molded underwire bra and the fact that you have one piece to do it all - bra, slip, and some control to smooth things out.  I highly recommend it.
