Feel-ine festive, this three-piece flannel set is made from soft cotton in a classic twill weave, complete with a button-front top, relaxed drawstring pants, and a matching headband. The coral backdrop is covered in cats sipping champagne and clinking flutes, finished with contrast piping and a cuff that cheekily reads “Let’s Get Fizzical”—purr-fect for holiday lounging, bubbly nightcaps, and curling up for a catnap.
