This is a gorgeous vintage dress made from a cotton rayon blend. It is labeled a S but I think it would fit a M or smaller L best. There is a tie in the back to adjust sizing. It is slightly sheer (see photos worn without slip) so I will send with the pictured slip. This dress has the most gorgeous shell buttons that remind me of the beaches of Kauai 🐚 🌊 This reminds me soooo much of christy dawn but at a fraction of the price, hence why I listed the first photo as a christy dawn dress that is very similar!
