The truth is that, if your clothes are not clean enough to go back in your wardrobe, they really need to go in the wash, not on your chair for wearing again.

If you've warn them and they're even slightly smelly or dirty, then you really don't want to wear them again, do you? So, wash them!

On the other hand, if they're neither of those things, they won't contaminate other things if they go back in with the clean stuff, so do that. It really is OK to put worn but clean stuff back in the 'drobe.

Similarly, if your garments are too crumpled to go back with the tidy stuff, they're too crumpled to wear, so press them again before putting them back.

Now, you might argue that some clothes will never get washed following this principle. In practice, this simply doesn't happen; you can tell when clothes need washing.

I gave up my own chair about 2 years ago, and can attest that the wash-or-wardrobe method works well in practice.

In summary, then, I'd say your challenge isn't to find a different resting place for half-worn clothes, but to see the problem differently. Clothes go back in the wardrobe or they go in the wash. There really is no middle ground.
