NFS, Size swap preferred - The lovely & HTF Nightingale Slip Dress in black, size small, NWT. Beautiful egret, moon & floral print; adjustable straps; lined; midi length; thigh high slits on both sides. Purchased recently from awesome, trusted Spell gal/Posher. Tried on only, a little too snug for me. Any manufacturer flaws pictured (teeny lighter dots on black in a few spots, tiny run at seam shown, one side stitching at slit slightly loose). FTO Only please - Not For Sale - looking to trade for same in M or L, possibly open to the other colorway or for the Renew items on my wishlist. ✌🦌🦄
