She’s cool for the winter! Demi Lovato wears revealing sheer crop top and pants as she performs at celeb-studded Jingle Ball in Illinois

Allstate Arena in Rosemont, Illinois hosted 103.5 KISS FM’s Jingle Ball 2017 on Wednesday, rolling out the red carpet for a star-studded guest list.

Among them was Demi Lovato, whose black turtlenecked crop top was sleeveless and went sheer over her décolletage.

The 25-year-old actress and singer complemented the top with a high-waisted pair of black trousers that were themselves often sheer.
