Large lace mini dress in white but fits like a M!

This was purchased off of a site like “cupshe” that I found one day scrolling Facebook. It came in and was a lot smaller than a usual large. It is definitely more of a medium and it is a mini length dress. It’s bright white, lightweight and would look cute with a jean jacket and boots to dress down or dress it up for a semi formal type of event. I never wore it.
