Your neighbor hood may not like clothes hanging out your window. It does look pretty nasty seeing clothes hanging outside windows. But I do understand your wanting to get some fresh air into your clothes. I have another suggestion that won't be as nice a fresh outside air but works for me. I partially dry my clothes in the dryer, then I place them on hangers and put on a rod in my laundry room. I have two fans that I turn on the damp clothes and they dry overnight. Perhaps you could spray them with some kind of nice smelling spray while they are drying with the fan(s). In good weather you could rig up a small rack in front of the window with screen in place and run a fan too. Once in a while I might want to wear a shirt that is still a bit wet. I will bring it upstairs and put the garment on a hanger on a door knob and face fan towards the garment to dry. Mostly, I dry my stuff this way to avoid shrinkage in the dryer.
