What are your best-kept secrets for keeping clothing fresh and crisp?

Wardrobe overcrowing is definitely a problem. When our clothing is all smushed up against other items it can't breathe! Big problem of mine... (I'm working on it). I notice that with some TLC my clothing stays lovely and fresh. But the items that get the most TLC from me are the ones that cost me the most... no shock there.

But here's the thing... I've noticed that no matter what I do certain clothing items seem to fail me after 1-3 wears. Expensive jeans seem to stretch out, t-shirts never look the same after washing them...
