This is a new sample dress that has never been altered. I am listing this as a size 8 because the actual sizing is more like a street size 8. But it is labeled as a 10 because it is a bridal size 10. Bridal sizes are different from regular street sizes and run much smaller. Although it hasn’t been worn for a wedding, this was probably tried by on in the bridal shop before being sold as a sample. Decided to go with another dress.
