Enroll in fashion school if you wish to be involved with the production of your fashion garments from beginning to end. Fashion school will teach you all of the technical aspects of sewing together a garment, how to navigate the design process and pattern-making, and how to market and sell your garments if that is your ultimate goal.
Enroll in a sewing class in your community. Check with your local community college or center to see if they offer sewing classes, check your local classifieds for a sewing teacher, or approach a local seamstress to see if she is willing to give private lessons. Sewing classes will teach you the technical aspects of sewing fashion garments from a pattern. This is the best option if you wish to sew fashions for your own use but do not want to be involved in the design process.
Purchase a learning to sew book or fashion design software in order to teach yourself the aspects of sewing fashion. While it is best to learn from a teacher, learning to sew on your own is possible with determination and the right tools. A learning to sew book can teach you the basics of sewing along with technical aspects of sewing fashion garments such as jeans and dresses. Fashion design software will teach you how to design and create patterns and garments, as well as work with manufacturers.
