Alessandra Ambrosio sizzled in a thigh-high slit, Camilla Belle was elegant in an illusion neckline, and Kim Kardashian West demonstrated the power of the maxi skirt. Here, the red carpet looks we couldn't get enough of this week.
Alessandra Ambrosio at The Omega House in Rio de Janeiro Party: When you're a supermodel, you can look fantastic in just about anything. Case in point: Alessandra Ambrosio this week in Rio. But her look was something to write home about: a white halter top, gold sandals, and a Misha Collection Astrid Skirt. This ensemble screamed engagement party, and would totally start the journey to your wedding with a sartorial bang. Her sleek hair and flawless skin were the perfect complements to the sultry getup, though you could easily wear a ponytail and an eye-catching lip for a pop of color.
Camilla Belle at The Omega House in Rio de Janeiro Party:Carolina Herrera is one of our favorite designers of all time. Whether it's bridal or the red carpet, few make a dress as beautiful as she does. Camilla Belle slipped on one of her designs this week in Rio: a Short-Sleeve Tulle-Embroidered Midi frock that was the epitome of elegance. Wear this number for your rehearsal dinner if you're looking to flaunt your decolletage. You'll definitely want to pull your hair away from your face to let the dress's neckline play centerstage — pulled back behind your ears like Camilla works, though we also love a simple chignon.

__Kim Kardashian at BlogHer 2016:__Fashion is all about bringing the boudoir to the street right now: slip dresses and nighty-inspired skirts are all the rage. Kim Kardashian is one of the fans of the trend, and chose a Nili Lotan Maya Skirt to uplift a white t-shirt this week. Her gold Gianvito Rossi sandals anchored her look — perfect for your bachelorette party or post-ceremony brunch. Her sleek angular bob is a great cut to choose if you're looking to switch up your hair for your wedding, though your voluminous natural curls or iron-created waves would pair amazingly well with this ensemble.
