To pull off the glitz and drama that a sheer, red-hot, feather-trimmed night robe requires, one must first have the kind of confidence that Serena Williams clearly carries.

Earlier this week on Instagram, the Grand Slam–winning tennis icon posted pictures of herself modeling the fiery number from a recent photo shoot. With some help from her team (hairstylist Angela Meadows, makeup artist Natasha Gross, stylist Kesha McLeod, and photographer Ronald Wayne), Williams evoked old Hollywood glamour as she posed against a dramatically lit staircase backdrop. Under the robe, Williams wore a maroon body-con minidress with red pumps.
