H&M maxi t-shirt with black dress / coverup in tan & black (L)

H&M maxi t-shirt dress / coverup in tan with black dashed pattern, almost batik-like. Maybe animal pattern? Very, very lightweight. 79% lyocell, 21% polyamide. No stretch. Two breast pockets in front, see pics (prop not included). Long slits up both sides at the bottom hem. Measurements in pics, oversized (size L). Machine wash cold, hang to dry. Never worn. In perfect shape! I bought this during a live show as part of a “not so mystery box” bundle. I’m keeping other items but reposhing this one—I’m too short to work a maxi dress.
