Rihanna In Mark Fast – 23rd Birthday Party

Rihanna celebrated her 23rd birthday with a Nivea sponsored party at a private residence in Beverly Hills on Sunday.

She shook her famous booty wearing a Mark Fast Spring 2011 dress.

Mark Fast’s voluptuous creations are designed to highlight the female form. This nude and purple handmade knit mini-dress with tassels does it effortlessly.

There are very few women who can actually work this look without fear – Rihanna and Kylie who is also huge fan of Mark Fast.

I think most women would be petrified to wear one of Mark’s sexy dresses, but then most of us don’t have fabulous figures like Rihanna and Kylie.
