I have a vintage Simplicity Style pattern # 2793 for a dress with a belt and pockets, and it can sleeveless or short sleeved. The dress has a back zipper, two lengths available and the belt clasp is purchased.  This pattern is a misses' sizes 8, 10, 12, 14, 16 and 18. 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.
