Elegant Floral Reversible Robe

I ordered this through and Instagram and it took over 2 months to ship plus some kind of hefty shipping costs. I loved and am keeping the pants but the robe has not made its way into my wardrobe after a couple of months. It’s brand new, never worn and in original box. I am 5’6” and it almost touched the floor. It falls like a maxi dress. XL is on the 10/12 side.
