If you are making a buff coat, there are commercial patterns. The pattern ought to tell you how much material is required, depending on your size.

no as far as i know its a custom design

on second thought but not to sound ignorant but what is a buff coat?

At the end of the 16th century firearms made plate armor obsolete. Some protection was still needed against sword cuts, so thick knee length leather coats, worn alone, or with a breast and back plate were introduced. The coats were made from a tan stiff "buffalo" leather. Buffalo were actually some sort of oxen. You can do a web search on buff coats.

OHHHH ok then yes that is what I need, thank you very much
