She’s beautiful with a great sense of style, and on Saturday (May 18), Camila Alves played host to a fashion show at Macy’s in Las Vegas.

The 31-year-old model, who is the store’s INC Brand Ambassador, wore jeans and a shimmery navy-and-white top under a sheer ¾ length cardigan as she posed with attendees.

Last week, the Brazilian-American beauty shared the secret to her great marriage to actor Matthew McConaughey, whom she wed in 2012.

"The main thing to always remember -- and I think it's important -- you and your partner came first before the kids," she told US Weekly."So even if it's taking a night here or a day there or a weekend, it's just very important to do."

The lovebirds began dating in 2006 and have three children together: Livingston, Levi, and their latest addition, Vida, who was born in December.
