The Seraphina Collection - Size 6 - Great for Bachelorette

I originally both this in a size 8 but it was too big. Sold it and repurchased and I’m 95% positive it is a size 6. 5% chance it may be size 4. I can’t find the listing I purchased it from a year ago. It was purchased unused and I had every intention of using it for my bachelorette and never got around to it. Bachelorette has came and gone. Undergarment that comes with it was never tried on. Item is NWT. I am a US6, size should be US 6/UK10 Dress comes from a UK brand that no longer makes it. Ptp is 15 inches. My bra size is 34b and this fits true to size based off the size chart. Comes from a smoke free home Bundle to save and send an offer :)
