Zimmermann Polka Dot Mini Dress

Size 0 Zimmermann mini dress. It has some light boning in the bodice. Fully lined. Side zipper. Kept in great condition - only sign of wear is on the armpits, there is some discoloration from spray tans / deoderant. I’ve had it dry cleaned, but have never really tried to fix the discoloration because it’s covered by the large ruffles. Its very mini. I’m 5’2” for length reference.
