I bought these tights in the summer and forgot to return them, but my loss is your gain. I have 3 pairs of these and they are wonderful. For whatever reason this color is not quite as stretchy as the other colors I own. I'm wide in the hip so need some extra stretch, but I'd say these are fairly true to the size chart. New with tags, never worn. Stored indoors in smoke free, pet free, and fragrance free home.
