Vintage Red Embellished Tiered Gown with Bell Sleeves

I’m not 100% sure what this is. So if you know please let me know! I am sure that it’s such a beautiful piece. It is a piece that I got with other vintage dresses. It is very long! And has very long sleeves, that I’m guessing need to be tied a certain way as there’s beading on the inside of the sleeves. As shown in the photo and video. Red mesh with beading and sequins! Elastic waist makes it good for many sizes. Flaws, small hole in the mesh of the waist band shown when stretched. Some sequins missing but minimal. Measurements: Pit to pit:21 inch Waist: non stretched 12 inches stretches to about 19 inches
