DESIGUAL Mandala Floral Print Designer Tubetop Dress

DESIGUAL Mandala Floral Print Designer Tubetop Dress Size tag has faded. I’m guessing it’s a medium/large…fits medium with a lot of room in the chest area room (so large on top). Please check the measurements and photos to make sure it’ll fit. In good pre-loved condition (I wasnt sure how straps were supposed to go so I tried it on the mannequin different ways)
