I have a Simplicity pattern # 1109 that features skirts with a back zipper, and length and trim variations. 

It is a misses' size H5 - this is sizes 6, 8, 10, 12 and 14. This is a brand new, 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 I will be glad to discount multiple purchases (10% off for two items, 15% off for three items and 20% off for four or more items). I also have this pattern in other sizes (Simplicity #0423).
