Thinking about going to fashion design school? I have been there done that, here are some things that you will need:

Sew Vac Direct - Family Sew Dress Form Professional Series
This is the first thing I bought when I got accepted into fashion design school way back in '99. Well the school actually made us buy one (I ended up buying 2). This is a key tool for a fashion designer and when you stop designing its a good looking piece just chillin in your house.

Brother LS2125I 10-Stitch Free-Arm Sewing Machine with Automatic 4-Step Buttonholer

This sewing machine got me through 4 years of fashion design school. It's simple to use, quiet, and gets the job done. A must for a fashion designer or a casual home sewer.
9 Heads: A Guide to Drawing Fashion
This book is the only fashion illustration book I didn't get rid of Amazon.com. I still use it to this day. It is the next best thing to having an art teacher walk you through everything and the book is amazing looking. So worth the money, you will keep it forever.
