Silky long dress XL black floral Hawaiian theme/casual party

This is a beautiful dress . The tag is missing, however, I believe it might be silk. Only because I have a lot of silk and I wouldn’t put this in with the regular wash. It’s in great condition and it’s fully lined with a Flowy light weight fabric. This is perfect for warm weather. It has a small ruffle at the bottom. Please let me know if you need any more measurements.
