Grant Gustin is no stranger to the red suit of DC's Scarlet Speedster. After all, he stars as the title character in Warner Bros.' TV take on The Flash, and has won the hearts of thousands of fans ever since he first donned the mask in the pilot. So while it wasn't especially surprising that the star decided to dress as The Flash for Halloween, his adorable choice in Halloween costumes was totally Instagram-worthy.
Seen above with co-star Tom Cavanaugh, Gustin opted for a Halloween store-brand muscle suit instead of his usual crimson get-up, wearing it in-between shoots for the hit CW show.
This isn't the first time that CW stars have parodied their on-screen personas. Last year, Gotham star Ben McKenzie dressed as the comic book counterpart of his character, Jim Gordon, at Heidi Klum's Halloween bash.
Gustin wasn't the only person that dressed up on set for Halloween, either. On the set of CW's Vertigo-inspired show, iZombie, the show's crew decided to get punny for the holiday.
The CW goes all-out for Halloween with a yearly 'CWHalloween' campaign on social media—did you dress up as one of their characters? (Because I did!) Share your costumes in the comments, too!
