It's time to break out the cow costume.

Chick-fil-A is offering free food on Tuesday to anyone who shows up at one of its locations — dressed as a cow.

AMERICA STILL LOVES CHICK-FIL-A MORE THAN ANY OTHER FAST-FOOD CHAIN

The offer comes amid celebrations of the fast-food chain's 15th annual Cow Appreciation Day, during which the company commemorates its "Eat Mor Chikin" cows.

Customers who visit one of the restaurants' 2,400 locations across the U.S. dressed up like a cow are eligible to receive a free entrée from opening until 7 p.m.

Cow costumes, per Chick-fil-A, are defined as anything "cow-like." That includes spotted accessories, a T-shirt with black and white spots, or "a cow hat or mask, etc."
