I bought a 9-10 kids set, a medium mens set and a large womens set, which the website advised would fit a UK 12. My son and partners PJs were perfect fits but mine was utterly unwearable as it was MASSIVE even though the label confirmed it was a women’s large UK 12. I could have got all 3 of us into the trousers they were so big. A very disappointing Xmas morning.
