AllSaints Sian Long Sleeve Dress Black NWT Size large

AllSaints Sian Long Sleeve Dress Black NWT Size large. Beautiful dress brand new with tags. Approximate measurements 37” shoulder to hem, 12” width at bust and 10” width at waist. Body con throughout - very slinky! Runs very small, in my opinion. :) Listed as a large on brand label and hang tag but measurements seem more in line with a small or extra small. Please keep that in mind. I did attempt to peek under the sticker on the hang tag but didn’t want to risk ruining the top sticker. L4
