I just went from long hair to something similar to Alyssa Millano's hair. I had too since I chemically straightened my hair and it was so damaged so it gave me a good push to finally do it. I'm glad I did. I think it looks cute but it can look sexy. It is really easy and quick to style now.
One thing I've noticed is I want to look more feminine. I tend to wear more skirts, lace, dresses, pencil skirts, etc. instead of dressing completely in my normal outfits.
Here's a pic of Alyssa to give you an idea...
