Everyone needs skelton clothes. I'm sure you're aksing yourself what on earth am I talking.
Skelton clothing, is like a skelton key, goes with everything or just about everything in your wardrobe, just like a skelton key opens all the locked doors.
Take for example, I have lots of black pants, and some printed skirts (and black of course), so just about all of the tops I own goes with just about everything.
If you pick mostly solids, then you have a huge wardrobe because just about everything goes with each and if the color is just a tid bit off, but doesn't hurt your eyes, then its monochromatic, which is always good.
