It was a big day for bride-to-be Kristin Cavallari at Mercedes-Benz Fashion Week Swim, who not only crawled down the catwalk in a bikini for the first time, but also modeled Diesel’s first glass bikini – and RadarOnline.com has the sexy photos!
Despite twittering about her nerves earlier in the day, The Hills bad girl looked sensational in the cobalt blue, one-shoulder number, which was embellished in shards of glass and inspired by SKYY Vodka’s bottle.
“It went well!” she tweeted after the show. “I was so nervous but its done!!! Party time!”
