Made in Britain and 100% authentic! This skirt is so beautiful! It is in incredible condition for its age, with no imperfections that stand out at all! (There’s always a possibility of an imperfection here or there on any vintage item, as vintage is not meant to be perfect) The tag has multiple sizes listed. Please ask any and all questions before purchasing! The last photo shows the skirt inside out. Laying flat, the waist measure 15-15 1/2 inches. Please refer to the photo! A UK 18 is equivalent to a U.S. size 16 according to Burberry.com today! But a lot of vintage clothing used to run a bit smaller than they do today. I would say this could run anywhere from a size U.S. size 10/12/14/ depending on how high up you like to wear your skirts. Please again refer to the measurement photo!!! Pre-1998/1999*, Burberry went by “Burberrys” and tags would say “Burberrys” “Burberrys Made in England” “Burberrys London Paris New York” and “Burberrys of London” depending on decade and if the item was sold/manufactured in England or overseas. Post-1998/9, they changed their name to simply “Burberry” and tags will say “Burberry London”.
