Swtddy Kids Girls Winter Warm Elastic Leggings Stretchy Fleece Tights Pants Thick Velvet Trousers (Tag Size M(for Height 110-125cm), Navy Blue)

Somewhat small despite picking the larger size. But very cozy and comfortable. My 4 year old wears this once or twice a week on cold days at her preschool and loves it. Will recommend it.
