It's still summer for Julianne Hough. Hough, 37, took to Instagram on Tuesday, December 23, to show off her figure while dancing around her Christmas tree in a barely-there look. She struck a pose in a black bralette top featuring triangle cups and straight straps. The Dancing With the Stars cohost mixed and matched her top with light-wash bottoms finished with thin string straps. She posed with her head tilted back and one hand on her hip in front of her decorated tree with presents surrounding it.
