Put on your fanciest gown and straighten that tie on your tux because tonight the Costume Designers Guild will present the 21st annual CDG Awards. Hosted by 13 Reasons Why actress and Grey’s Anatomy alum Kate Walsh, the award ceremony celebrates — you guessed it — excellence in costume design. Diane Haithman will be on the ground at the Beverly Hilton for the event while Dino-Ray Ramos will be lending an assist with the live blog.
