Like someone before me said, make sure you step your iron game up. Light steam, basic, unscented spray and utilize those hangers. There is a reason you own 400, right? They help.
Colors inside out. Stuff socks purportionately into shoes to keep the toes from creasing and stop walking the fu*king mud or grass. Use the Mr. Clean Magic White Eraser, it works wonders. Shoe polish helps too.
For Hoodies ... DRY CLEAN! Polos, yes keep the top button buttoned while hanging, and while wearning tuck them under your a.ss if you can't iron. If you can, who gives a sh*t.
Also, step it up and buy clothes that aren't necessarily brand names when it comes to wearing complimentary colors that flow well with a fit. 5 for $20's at Foot Locker help and also, yes use Febreeze on clothes in the closet.
Most of this is common sense. It isn't rocket science people. Peace.
