I saw this shirt on Amazon and had to have it. (Granted, the soft kitty one was also tempting.) But I don’t like wearing regular T-shirts, so I changed it into a girly fitted shirt with puffy sleeves.
Doing so wasn’t facilitated by the fact that the original shirt was completely lop-sided, almost a parallellogram. I took out the sleeves, cut several cm off the sides of the shirt, and shortened it. Then I sewed the sleeves back into the now smaller arm holes, without changing the size of the sleeves. I gathered them both at the shoulder and in the middle of the arm band, to make them puffy.
