Grammys 2019 Best Dressed Stars on the Red Carpet

Our hostess with the mostess, Alicia Keys, knows how to make a statement, and this body-hugging button-down gown is the perfect fit for her. She looks ready for business but also fresh and fun. Meanwhile, the complimentary pops of red in Swizz Beatz's suit are divine.

Alone, the pink jacket might not sing, but styled with those easy slippers and handkerchief, this is a rather elegant little ensemble.

Nevermind that strange facial hair, Ricky Martin looks like a million bucks in this simple two-piece suit and sneakers combo. It doesn't hurt that he's got the best accessory of the night.

The cut of Kaskade's textured blazer could be a wee bit longer, but the texture of the material is inviting, and the broach and shades make it pop.

Bebe Rexha told Ryan Seacrest that she felt like a princess in this and that this was her opportunity to show that she was proud of her body type. We might not be crazy about the fitting of the bodice or how many layers of fabric are in this skirt, but the fact that she felt so good about herself definitely came through here.

There's something pretty poetic about the way the members of Bring Me the Horizon decided to subtly match suits, with Oliver Sykes doing the heavy lifting with the floral embellishments.

At first, we had Cardi B picked as one of the worst of the night because, let's be honest. This kinda looks like she got stuck between channeling from Ursula the Sea Witch and Kim Kardashian's Paper Magazine photo shoot. But the more we saw it, the more we realized it was catching our attention, and you know what? That's the point, so she wins.

This is like Steel Magnolias for the 31st Century, and it's so appropriate for her.

The shape of this is intriguing enough, then add this eye-popping color and her manicured coif, and it's a winning look.

This velvet blazer is a new classic.
