Lady C Leather is really neat. It's a bit off the beaten path for tourists, but worth the trip.
When I got in, I immediately started to poke around and was offered friendly assistance by the owner. Lady C is super, her kindness and helpful attitude made me feel really welcome. And as someone who tends to frequent more alternative shops in every major city I visit, I've had all sorts of 'tudes from people who think their whips don't stink...
Expect to get great customer service and a lot of information on pretty much anything you'd want to know about corsetry, the 'scene', etc.
I really enjoyed my trip to Lady C and will be back next time I visit Vegas.
