Sizes 70-80 Since they have different patterns, they're also recommended for twins! In our house, we dressed our boy-girl twins in them. I really liked them because the necklines didn't stretch out easily, so I bought several extra, but I'm selling them to organize. These are cute long-sleeved T-shirts with a bear and a dog (?). The neckline opens wide with buttons, making them easy to put on and take off.
