I have a McCall's 7 Easy Pieces maternity pattern # 3131 that features dresses, tops, a pull-on skirt and pull-on pants in two lengths.  The package contains instructions and patterns for the following:

• Dress A or top B has V-neckline and short sleeves; dress C or top D has shoulder straps; top B or D has side slits.
• Skirt or pants have an elasticized waist; skirt also has lower flounce.
• Dress, top and pants have stitched or hand-sewn hems.

This is a misses' sizes Extra-Small (4-6), Small (8-10) and Medium (12-14). It 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.
