Thank you so so much
Sadly for their coat's pattern I can't really help you since we had some help to make it. The only advice I can give you is that when you make their sleeves, we had the problem of not being able to lift our arms up, so we decided to sew a diamond-shaped piece of stretch fabric under the armpit that connected the bodice to the rest of the sleeve. I hope you understand what I mean ;;
However if you're looking for patterns to put together you can always look for something with a similar collar and alter the rest; I don't know your skill level, but collars are pretty hard to modify for me. For the holes in the sleeves I recommend just sewing a test jacket and cutting it out. You can modify your pattern to fit the hole. (Hopefully you understand, if you ever need me to explain something better just ask ;;; )
Always nice to meet other AnoKano cosplayers, there aren't many out there!
Don't be shy to ask if you ever need something else (or need something explained more clearly!) English isn't my first language so sentences might be structured weird. Sorry about that!
