As soon as I get home from work, I hang up my suiting, dress pants, skirts, dresses, etc. I don't purposely air them out, but rather just let them hang for the remainder of the week until I'm ready to put them away. And I alternate Dryel and dry cleaning. I sit behind a desk all day and only really get them dirty when I have a run-in with lunch ... usually a blog of greasy ranch dressing.
I wear my jeans usually just for short periods of time to run errands, etc. and don't wash them often at all to avoid fading as I usually lean towards dark wash jeans. Everything else gets tossed in the hamper.
