Dreamy: Rihanna's Birthday Dress

I NEED to know who makes this dress! It's sexy, fun, and adorable.

Rihanna sported this lovely creation for her Birthday on Feb 23rd in L.A. at a private residence. Although that mop on her head nearly killed the whole look, the fabness of the dress definitely saved the day.

I'm on a hunt to find out who made this perfectly fitted creation...

If you know please leave a comment!!

UPDATE: A reader brought to my attention that this dress is from the Mark Fast SS/2011 collection! Check out the runway look below.
