The “groutfit,” or gray outfit, is often reserved for lounging around the house, stuffy boardrooms, or late-night trips to the airport. For Beyoncé, however, it was the perfect choice for a trip to Broadway. During the weekend the Cowboy Carter singer reunites with her Destiny’s Child bandmates Kelly Rowland and Michelle Williams to support the latter’s performance in the new series Death becomes her musical.

Beyoncé started her look with a knit top, tucked into cut-off hot pants that were small enough to classify as briefs. The singer compensated for the length of her shorts with an oversized suit jacket and suede heel boots that reached her knees. She then added a gray baseball cap, statement nerd glasses and an elongated black clutch.

While Beyoncé previously rocked all-gray in more exaggerated ways, this time she left the glitz and glamor to the Broadway professionals. Beyoncé and Rowland snuck into the opening night crowd Death becomes her performing with Megan Hilty, Jennifer Sinard and their former bandmate Williams as Viola Van Horn. After the performance, Beyoncé and Rowland met Williams backstage, who was all decked out in her stage clothes, hair and makeup.

Beyoncé documented the evening on her Instagram with a series of photos that she captioned with the words “My Belle.” The singer’s mother, Tina Knowles, was also in attendance.

“It’s always great to see Destiny’s Child together,” Ms. Tina wrote on Instagram. “At the Death becomes her recently premiered on Broadway in New York City, we watched Michelle kill this role! She said like an angel and looked like a goddess! Ride or die friends who support and love each other.
