Isis vintage relaxed shift dress

vintage comfy black relaxed tank top dress. used, but still good condition. there’s a tiny zipper pocket on the front which leads me to believe, it might be a yoga or athleisure brand. has a cool sort of gothic design on the top back of the dress- seen in 6th picture. could be dressed up like first picture, or keep it casual for errands. 🖤let me know if you have any questions on the item 🖤
