Now this is how you celebrate St. Patrick's Day. While some may opt for a green accessory instead of donning the color head-to-toe for the holiday, Neil Patrick Harris's twins are not among them. In honor of the holiday, the proud dad took to Instagram to share a photo of Harper and Gideon, and it's about as festive as can be.

"Happy St. Patrick's Day from NPH, David, and these two leprechauns. (Photo by @dbelicious) #blarney," Harris captioned the photo. In it, both Gideon and Harper get into the St. Paddy's spirit with oversized glittered green sunglasses and green-tinged carnations. But that's just the tips of the festive iceberg when it comes to the 6-year-olds's outfits. For her part, Harper is also wearing a green plaid skirt, while Gideon is donning olive green pants and a pair of suspenders. So. Cute.
