Country's biggest stars donned their best looks to walk the red -- er, blue -- carpet at the 2018 ACM Awards. The annual awards ceremony is taking place in Las Vegas, Nev., on Sunday night (April 15).

Readers can flip through the photo gallery above to see all of the looks from the 2018 ACM Awards red carpet. Many of the artists are wearing gold pins with the numbers 851, 58 and 1. The initiative is a way to honor the victims of the Route 91 Harvest Festival shooting.

It's unclear where the gold pin initiative started, but 851 is for the 851 people injured during the shooting on Oct. 1 at the 2017 Route 91 Harvest Festival in Las Vegas, Nev.; 58 is for the 58 people who were killed during the tragedy; and 1 represents unity. "You are with us every single night in every single town," explains a card about the gold pin initiative.

The 2018 ACM Awards are set to air live on CBS beginning at 8PM ET. Reba McEntire will be hosting the show.
