Brenda Monochrome plaid skirt (from Kerina Mango)

I purchased this beautiful plaid skirt from Kerina Mango https://kerinamango.com/product/flare-plaid-skirt-monochrome-super-rare/ but it no longer fits me. In perfect condition, only tried on at home. It is thick and wooly, great for winter. I also have the coloured version available! It is lined with a side zipper. Waist measures 12.5” when laid flat.
