Burberry - vintage trench coat 12 Long

Burberry size 12 (long) vintage trench coat. In preloved condition with wear appropriate for age, with stains at bottom of coat. Shouldn’t be noticeable when wearing because of the way it sits. Might be able to be professionally removed. Missing button on right pocket. Since this is priced at over $500, it will be authenticated by Poshmark before it gets shipped to you. *last photo is of Burberry’s size chart.
