Julianne Hough's Dancing with the Stars fit features very unusual detail

Dancing with the Stars is back for its 33rd season, and host Julianne Hough stole the show in a gorgeous little black skirt with a very unusual detail.

She walked on to the stage with co-host Alfonso Ribeiro, and the pair introduced their 12 celebrity contestants which includes Olympian Ilona Moher and actress Tori Spelling.

The opening number saw the professionals dancer perform an incredibly high-octane number to dance remix of Celine Dion's "I'm Alive".

The Bachelor's Joey Grazedei was the first performer of the night, and the contestants were asked to pick a song that they felt was their "personal anthem" to perform their first dance of the evening.

Joey's professional partner Jenna Jameson picked a cha-cha to Tyler Hubbard's "Dancing in the Country".
