I wore this dress for a wedding in March 2020 after COVID-19 delayed the original dresses. It is from Birdy Grey (birdygrey.com). The actual size is a large, as indicated in one of the photos. The listed sizes do not provide for "large" sizes, so I approximated the size as a 10.
The dress includes an extra sash and the original sash. I did not alter the dress before wearing it, and it has normal wear and is in very good condition; it just needs a dry-cleaning to be perfect. Please let me know if you have any questions!
