Jenna Johnson can rock a naked dress like no other. The Dancing With the Stars pro, 31, showed off her sexy side in a barely-there look on Monday, December 15, while enjoying a holiday party. In the pic, she flexed her rock-hard abs in a burgundy red sheer top featuring a mock neck, long sleeves and thumb holes. Underneath, Johnson gave her followers a look at her lingerie, which featured a red bra adorned with lace. Johnson completed her look with a low-waisted skirt adorned with a feathered hem and a thigh-high slit.
