With so many dresses from the Gucci Spring 2011 collection flying aroung, we're bound to see a few doubles here and there.

Just one week after Charlotte Casiraghi wore a belted, purple and peach knot dress to the Il Mondo Vi Appartiene Dinner in Venice, Kim Kardashian was spotted in the same color-blocked Gucci creation (with her beloved teal and gold ankle-strap heels) to the launch party for her new fragrance in London.

While Kim's confidence definitely did the dress justice, I can't help but think her curvy figure competed with the design. Whereas Charlotte's frame is model-made, her slouchy stance sold the look a little short. This one is a toss-up for me.
