Keith Urban's ACM Awards fashion is on point, but has it always been? Early on the hitmaker established a signature look and color he has rarely strayed from. Even the "best" look on this list is classic Keith Urban.

Rarely does Urban add color to his red carpet wardrobe — both he and wife Nicole Kidman usually choose dark outfits, most often black — but on one occasion Urban broke the trend and found a bright orange dress shirt that we'll politely say is not our favorite. Another year he went tan, and to be honest, it was a charming surprise that ranks high on this list.

The 2018 ACM Awards are on April 15 on CBS, and if Urban and Kidman walk together it will be their seventh time together on the Las Vegas red carpet. Here you'll find photos from every year except two since 2001. (Urban didn't attend in 2007, and in 2005 he appeared via satellite to accept awards.) Enjoy this trip down ACM memory lane ... there have been some tremendous outfits.

Remember: The best way to watch the ACM Awards is on TV, with TOC on your phone.
