Decided to make a little chart like this for people that need it. It's also something really quick I can send to customers. It was inspired by this!!

I've been sending that to people I need measurements from but decided it'd be better if I just made my own.

It's pretty self explanatory, if you have any questions let me know. Also feel free to use this for your own fursuiting needs, just please credit me and don't repost without my permission!
