Lady Gaga's whole beauty look was on point, but we were especially enamored with the emerald cat eye she wore. Celebrity makeup artist Sarah Tanno blended a mixture of Shiseido Shimmering Cream Eye Color in Tin, Mist and Caviar to give the look a sultry, smoky feel.
Celebrity hairstylist Frederic Aspiras used Matrix StyleLink Height Riser to add volume and texture to the Grammy winner's loose, sexy hairstyle.

Queen Bey
We'd believe that Beyoncé really did wake up like this. The Grammy winner's subtle makeup and flowing hairstyle were perfection.

Futuristic Flair
We loved everything about Jessie J's look, from her gelled-back hairdo to her wine-colored lips. Her creamy, flawless skin had a hint of bronzer to keep the look soft, not harsh.

Another day, another rainbow hair color spotted on Katy Perry. This lavender hue looked amazing with her ultra-sparkly Zuhair Murad dress (fresh from the Paris runway) and mega-long lashes (courtesy of Covergirl Full Lash Bloom Mascara).
Rihanna arrived fashionably late wearing a pink, poufy, cupcake-esque gown, which paired well with her sleek-yet-artfully-messy bun, nude lipstick and glowing complexion.
The Grammys dress code is a bit different from that of the Golden Globes or the Oscars (see: anything worn by Lady Gaga). The outfits are edgier, and so is the hair and makeup. This year was no exception. The biggest names in music stepped out wearing everything from emerald liner to graphic cat eyes. Here, the most adventurous, stunning beauty looks from the 2015 Grammys.
