Tailoring:The Classic Guide to Sewing the Perfect Jacket, you'll have what you need. This book takes you step-by-step through the process of making a beautifully tailored jacket using hand, machine and fusible tailoring techniques, which you can mix and match to meet your needs.
Obviously, one blog post won't teach you everything you need to know about tailoring, but if you are interested in learning more, I highly recommend the book I referenced above as well as a few blogs that I found useful:
Made By Hand - The Great Sartorial Debate - This is a wonderful blog, written by a professional tailor. He showcases his own amazing work as well as taking apart bespoke garments to examine. Fascinating!
Sherry's RTW Tailoring Sew Along - A collection of tutorials to help achieve a high-end RTW finish to your tailored garments. The focus is on industry secrets, many techniques are by machine rather than hand.
Gertie's Lady Grey Sew Along - Gretchen, of Gertie's New Blog For Better Sewing, takes us along as she hand tailors her Lady Grey coat. She has tons of tips, tricks and great tutorials.
Tomorrow I'll talk about a couple of finishing touches - lining your jacket and making bound buttonholes. Stay tuned!
