Mystery dress. Sleeveless floral lined dress with very few details.

I found this dress at a consignment shop and although it looks great dressed up with heels or down with a denim jacket, I find the shell/ inner layer rather clingy and leaves me feeling exposed while in line at the checkout (still, I don’t get a discount.) This would likely be perfect for a taller, leaner frame (doesn’t everything?🙄 or with spanx or an exorcism). Although it says XL on the tag, this is misleading and it would look great on someone m/l. This is so pretty- the low price reflects the risk involved.
