[Lucid:]

^ Galla's tip is really good. I do this too, but my preferred color has changed so often I've had to buy a lot of colors anyway!

I have a solid stock of dirt cheap simple commons in every color. Bras, Kenny hair, socks, a couple accessories. This gives me flexibility to use blocks of any color in various parts of the body. Socks are extremely helpful as I find most of our leg gear doesn't suit my personal style.
