How to draw a fit & flare dress flat in Illustrator

Open Flat Library in Adobe Illustrator and go to Dresses.
Choose Fit & Flare Dress from the pictures. It is drawn on the template, front and back.
Pull the blue points to change its length, width, neck and sleeve. The front and back redraw together, and the figure stops you going too tight.
Insert it into your document as clean, named layers, and keep working by hand.
