Moooove over Tom Ford, Vera Wang and Marc Jacobs, the bovine look is in — at least for today.

Atlanta-based Chick-fil-A is encouraging fans of the brand to dress up in their favorite cow-attire today during the company’s 12th Annual Chick-fil-A “Cow Appreciation Day.”

Adults who show up in their bovine finery get a Chick-fil-A entree while costumed children can receive a kid’s meal.

“Cow Appreciation Day is the one day where it’s okay to dress ‘udderly’ crazy and get rewarded for it,” said Jon Bridges, Chick-fil-A’s senior vice president and chief marketing officer.

The chain is encouraging customers to share pictures of their costumes on social media by using the hashtag #CowAppreciationDay
