Hair and clothes are the easiest. Hair's less expensive overall and can make a more dramatic difference, because it is closer to your face, which is what most people look at first. But, it does take longer to change back (look at me - I know! LOL!)
Also, do you wear glasses/ contacts that you could switch back to the other? This is a change on the face that makes a difference. A change in makeup - especially now that we are changing seasons, you can head to Ulta or Sephora and get a free makeover and tips and get a whole new look! (I love the way makeup makes me feel!) I also really love jewelry, I can change the whole way the same outfit feels by the type of jewelry or accesories (like scarf, hat, etc.) that I put with it.
Now that I'm bald, I'm being extrememly bold in dressing, and tryiung all sorts of crazy things! It's like I lost my hair I lost my inhibitions (or a least the ones that relate to dressing wildly - I still don't do miniskirts or tight lowcut stuff!) <img src="/images/graemlins/shocked.gif" alt="" /> <img src="/images/graemlins/grin.gif" alt="" />
