People around the country are preparing for Halloween in a couple of weeks by putting together costumes for trick-or-treating, parties, and much more. Dunkin’ is encouraging its fans to get creative with their costumes in a new contest.

Beginning on Wednesday, October 17 and continuing through Thursday, November 1, fans can post their special Dunkin’-themed costumes on Instagram using the hashtag #DunkinDressUpContest. Each person will be entered to win a grand prize of $1,000 and a year’s worth of Dunkin’ coffee.

Additionally, a different winner will be selected each week to receive a $100 Dunkin’ gift card. The contest is open to adults 18 years of age or older, and only residents of the 50 United States or the District of Columbia.

The company is also celebrating Halloween with two themed donuts. The Halloween Oreo Donut is a yeast donut filled with vanilla buttercream, topped with chocolate icing and Oreo cookie crumbles, and drizzled with a Halloween-themed dark orange icing. The other themed donut is the returning Spider Donut, which features an orange-frosted donut with a “spider” in the middle made from a glazed chocolate Munchkins donut hole with chocolate drizzle for the spider legs and orange drizzle for the eyes.
