Katy Perry
...Menopause hot flash.
dwl
I'm just playing. 
Katy Perry brandished a mint green Gucci Dress I love the dress, I love the hair,and I like the simplicity of the MakeUp (although I would add a bit more colour to her face, possibly making the lip a little richer or a little pinker). All in all, Katy brandished her Gucci dress well.
Rihanna's hair brings me back to her 'Pon de Replay ' days
Rihanna brandished a sheer red custom made Azzedine Alaia dress. I love the colour and the design. I see Rih is feeling like a good girl today.Rihanna and her current beau, Chris Brown.
Kelly you look good, won't you back that thang up.
Kelly Rowland brandished a Georges Chakra dress and she is banging out. I wish Kelly would have made her bangs less thick and more wispy.
Rick Ross on the red carpet of the 2013 Grammy Awards. Do you think he looks dapper?
Rick Ross brandished a custom made Tom Ford suit and carried a cigar to complete the look.

Alicia Keys brandished an Azzedine Alaia dress.I love the dress but I wish her hair, MakeUp and Jewellery were different. V.S.O.P. would have made her jewellery less serious and more funky.

Jennifer Lopez brandished an Anthony Vaccarello dress and a Top Not Bun.
Miranda Lambert brandished a Roberto Cavalli dress. I like this look on Miranda, it is that "grown woman" sexy and the tan is just the perfect compliment.

Florence Welch freaking killed it.
All of the celebrities above were the best dressed at the 55th Annual 2013 Grammy Awards.
