On This Week's Best-Dressed List, Gabrielle Union Pulls A Hat Trick

This week's best-dressed list might be one of our favorites this year.

Not only did one actress make the list THREE different times (major shout out to Gabrielle Union), but Caitlyn Jenner wowed in one of her most elegant looks to date and "Revenge" actress Ashley Madekwe stole the show in a culotte-crop-top combo for the ages.

Check out our favorite looks of the week and let us know if you agree with our picks.

A bomber jacket can dress down any look.

Gabrielle Union in Rag & Bone: A slip dress in the summer is one of the sexiest looks, but Union toughened up her outfit by adding a bomber jacket. We love the mix of masculine and feminine elements and her bold red lipstick just puts her ensemble over the top.
A little lace can go a long way.

Gabrielle Union in Noam Hanoch:Va-va-voom! This could be one of the best jumpsuits in best-dressed history. It fits her like a glove and the lace detailing adds a little something special to make her stand out from the crowd.
If you're going to wear a busy dress, stick with neutral colors.

Gabrielle Union in Self-Portrait: This dress further proves Union's versatility. Here, her look is a tad more girlie and polished, but her undone hair and minimal makeup ensure the actress looks effortless.

Caitlyn Jenner in Atelier Versace: There was no doubt that all eyes would be on Jenner at the ESPY Awards on Thursday night and this gown was the perfect choice for her big day. It was simple, elegant and classic, and worked to enhance her natural beauty instead of detract from it.

A black and white pattern is a good starting point for women who don't like prints.

Lea Michele in Zimmermann: Talk about knowing how to dress your body! This frock fits the actress' every curve and the small-scale print adds just the right amount of visual interest.
An interesting top can make an outfit.

Ashley Madekwe in Self-Portrait: We NEED this entire outfit. Madekwe had us with her culottes, but her asymmetrical crop top is really sealing the deal.
Brown and white are a great color combination.

Gigi Hadid: Hadid looks bright and fresh in her white dress, which she smartly belted to help define her waist. We love how she knotted her leather belt -- this is a trick we'll definitely be stealing.
