I want to make a classic 3-piece suit for my girlfriend to wear to a wedding. I've made one tailored suit before, but have never drafted the pattern for a suit jacket myself.

Can anybody recommend a good source or drafting guide I can work from? Particularly for the jacket? Or, a pattern recommendation that I could use as a base to alter?

Looking for single breasted, peak lapel. Thanks!
