I have a Burda pattern #2584 that features an easy sleeveless dress that is semi-fitted, has a back zipper and is available in two lengths. 

 It is a size 8, 10, 12, 14, 16, and 18. This is an uncut, factory folded pattern - the package has light wear and is priced accordingly. 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 (10% off for two items, 15% off for three items and 20% off for four or more items).
