The pics are legit but don't go by the pictures alone. Blue Pearl takes awesome photos and except for a few of the girls (Heather being the top of that list) they do not look as good in person
There are 4 spas in the city with the best looking girls on average: Platinum, HFH, Allure, SRM
Of your list above I'd say Nicole is the best looking in my books (I've not laid eyes on Kathie though). Brittney's body is totally awesome but facially some people aren't as impressed although she's still attractive. I'm fine with her looks but she's not the supermodel that you'd be hoping for. For natural beauty I'd suggest Nancy. Allegra, Kelly, Danielle are also very good. I've hear Jordan is a knockout.
Don't go there for a regular massage though.
