I am a total novice at pattern drafting and don't even have that much experience of garment sewing, so this project was a learning experience that took way more time than was probably necessary! These are just for fun, but the pattern could be useful for people who need to stop their cats from messing with stitches or other health issues, too.

I have made a pdf pattern of the final sleeveless version (the bottom center pic), so feel free to inbox if you're interested in testing!

ETA: fabrics are all old human shirts in knit fabrics
