Adidas tank top. The numbering on the back is cute (*≧∀≦*) Size is S, but it should fit someone who usually wears M. ☆Length→57cm ☆Width→45cm (flat measurement) ⚠︎I've worn it a few times, but I don't see any damage. Please refrain from purchasing if you are concerned, as it is stored at home and inspected by an amateur (❁´◡`❁)*✲゜*
