According to Business Insider, "On Wednesday, Aubrey Plaza attended the premiere of her upcoming film " Child's Play" at ArcLight in Hollywood, California. For the red-carpet event, Plaza donned a floral dress, green heels, and a hair clip shaped like a knife. The knife-shaped barrette retails for $32, and is sold by Vinca, an online jewelry brand from Texas." Fans went crazy for the knife on Twitter. They absolutely loved Plaza's boldness and eclectic style.
