I have a vintage Simplicity 'Full Figure Solutions' pattern # 7343 that uses the 'H O A X System' by Mary Duffy to flatter your body type.  It contains the instructions and patterns for the following:

• Tunic A, B has round neckline, bust darts, back zipper, shaped hemline and side slits.  A has long two pieces sleeves with button trim. B has short sleeves.
• Pull-on pants and knee length skirt have elastic casing.  Skirt has back vent.
• Wrap has narrowly hemmed edges.  Reverse side of wrap will show when worn.

It is a women's size FF - this is sizes 18W, 20W, 22W and 24W.  This is an out of production, uncut pattern.  It is from a smoke-free home and shipping is free in the U.S.  Please check my other listings - I have many other patterns and will be glad to discount multiple purchases.
