This is a set of two T-shirts, one from ALGY and one from Lovetoxic. They are labeled as size 150 and 160, but I wore them around the same time, so I don't think there's much difference in size. The ALGY shirt has slits on both shoulders. It doesn't expose much skin, like a shoulder-baring top. I liked wearing them, so there is some pilling and wear, but I think they can still be worn (*^^*) Not sold separately. ALGY Lovetoxic ALGY Love Toki (short for Lovetoxic) Teen T-shirt M size
