Kristin Cavallari threw on an interesting bathing suit yesterday to pose during Miami's Swim Fashion Week on behalf of Skyy and Diesel. She gamely posed for a photo op in a pool, then headed inside the Raleigh Hotel to walk during Diesel's show. To take the edge off, Kristin tweeted, "Hair and makeup time . . . [the catwalk]'s getting closer! Definitely having a glass of champagne before I walk the runway." There have been plenty of Kristin Cavallari bikini sightings in the last few months, since she announced her engagement to NFL player Jay Cutler. Jay left his football duties temporarily, so that he could be with Kristin in Florida to offer his support as she works.

It's not exactly the way we wore our knotted tops in the '90s, but the easy-chic, slightly undone feel that comes with that tied top is back. We love the nonchalance of a knotted top with high-waist denim, or over our favorite printed sundresses like we've seen on celebrities. That said, we're taking styling notes from these lovely ladies. From AnnaLynne McCord's '70s-style take to Kristin Cavallari's breezy elegance, click through for a celebrity-inspired tutorial in outfitting your knotted tops for Summer.

Gwyneth Paltrow stepped out in a daring white Pucci dress for the premiere of Country Strong in LA last night. The InStyle cover girl was joined by her costars Leighton Meester, who wore a pink Christian Dior mini, Garrett Hedlund, and Tim McGraw, who had wife Faith Hill by his side. Tim and Faith also supported Gwyneth at her Hollywood Walk of Fame ceremony earlier this week. The musical movie was nominated for a Best Song Golden Globe, after Gwyneth showed off her singing voice at the CMAs and on Glee, and we'll get to see her take the stage on the big screen when the film hits theaters in limited release Dec. 22 and more theaters on Jan. 7.
