In the midwest I've had luck with Kohl's for long skirts and maxi-dresses. Often the dresses are sleeveless themselves but can be topped with a nice jacket or a cardigan sweater for modesty. The store offers additional percent off discounts too, which can be added to clearance purchases. Depending on the size jacket needed, there are always decent and affordable ones on the clearance racks, suitable for business attire. Helps to shop off-season to get the best deal. Right now the longer style skirts are popular, so many are available. Just be sure to avoid the nasty, clingy fabrics, which are not flattering on anyone.
