Corset Dress

Blue and White Dressfo corset dress. Perfect new condition, without tags. I bought this as the front of the tag says XXL, however it did not fit. On the backside of the tag it actually shows size 12. The dress did fit on me but won’t zip. When it’s pulled tight it’s much smaller, along that size 12 range. But will not fit a typical 2XL size. My normal is size 18 in dresses. Super cute Alice in Wonderland vibes.
