Fredrick's is funny. It has the reputation of being the 'trashy' lingerie store, but a lot of their stuff ISN'T crotchless or covered in marabou and to find that corset/bra that is the only thing that will work with that special event dress, this is the place in town to go.
I don't know what more to say. If you need support that can't be slippin' down your shoulders you will find it here. Those little silicone cups that you stick on? Surprisingly effective. Their stuff is slightly expensive, but it's well made and lasts forever. I've had a corset from here for years that is just stunning but also functional.
It's just too bad they no longer have the wig wall.
