It's a navy face off for Rihanna & Kim Kardashian!  Both ladies recently rocked a chic navy long sleeved dress from Givenchy.  But decide who ran the look best inside...

Rihanna stepped out for her grandmother Dolly's funeral in Manhattan a week ago in the long sleeved Givenchy jersey shift dress ($1,510) with a V-neck cross-over pleated top.  The pop starlet may have been grieving, but she still made sure to keep up a chic appearance to Honor her grandma.  The "Take Care" singer, rocking her hair in a bun with a side swept bang, paired her curve hugging dress with gold ankle strapped sandals, a few flashy rings, and a pair of shades.

Yesterday, Kim Kardashian made an appearance at her family's new DASH L.A. store opening...with her boyfriend Kanye West on her arm.  The reality chick donned the same navy Givenchy dress (a departure form her usual black & white looks these days), but scrunched the sleeves up to 3/4 length.  And she paired it with black & white snakeskin Louboutin pumps.  Kim complimented her look with a high ponytail and a couple of small necklaces.

So....

WHO ROCKED IT BEST?!
