Grammy Awards 2017: Best and worst dressed

We can pretty much say with full confidence that we've seen it all after the 2017 Grammy Awards.

Stars hit the red carpet for music's biggest night on Sunday in a bevy of outrageous fashions -- and surprisingly it wasn't Lady Gaga who rocked one of the most riskiest looks of the night!

Halsey showed up braless in a sapphire blue silk ensemble that was a wardrobe malfunction waiting to happen! But it was pop star Girl Crush's colorful outfit that heads scratching -- it looked she jumped into the ball pit at a nearby McDonald's before hitting the red carpet. Singer Jacqueline Van Bierk also showed up in a dress covered in CDs, but we simply have no words.

Of course, there were plenty of red carpet veterans that made up for the walking fashion disasters. Carrie Underwood and Faith Hill rocked similar red ensembles -- and they both looked flawless! Meanwhile, Jennifer Lopez slayed, yet again, in a lavender-hued gown with a sexy keyhole cutout.

Check out all the best and worst looks of the night in the slideshow above!
