Formal dress - long sleeveless with removable jacket

This dress is strapless with removable jacket that is off the shoulder. It has a slit up the back to make walking easier. The tag reads 5/6 I’m about 5’ 6” or 5’7” when I wore. The color is more fuschia/light purple. The jacket has snaps to keep jacket closed. Wish I were thin enough to wear again but not likely. If you are slender this dress looks beautiful on!
