Demi Lovato has been a fan of the flattering plunging neckline all summer. The star recently wore it when she sang the National Anthem at the Mayweather vs. McGregor fight and also rocked a memorable plunging pantsuit ensemble during a press appearance in New York last month.

Now she’s back with yet another eye-catching look that took the plunge to the next level at this year’s Brent Shapiro Foundation for Alcohol and Drug Prevention Summer Spectacular, held in Los Angeles. Lovato debuted a bold Bibhu Mohapatra red dress with a low peek-a-boo cutout, which made for memorable formal wear one. She continued the show-stopping outfit with matching $800 Gianvito Rossi open-toed sandals. The Italian pumps were made with an elegant velvet material that completely covered the shoe and featured a 4-inch heel.

The Grammy-nominated singer made a strong case for red, and we hope she keeps the color going in her wardrobe.
