Women's plus size ski pants (run big!)

Free country plus size ski pants. Size 2xl. I wear an 18/20 or 1-2x and these were way too big. Reviews on the website said they ran big but ski/snow pants usually fit me small. I attached their size guide but I feel these are more 20/22 or 3xl. Wore only one time skiing and with a layer of long underwear on I stayed warm and dry.
