Miss Magnum,
Let me say that I believe it would be very difficult to ruin your looks with something as simple as a bad haircut or a bad hair day. Running face first into a speeding train, thermonuclear blast....something like that may do it.
I may be a strange one but that tussled just got out of bed look is HOT and every time I've seen it I've been glad I did.
I also love it when women who normally part their hair in the middle, part it on the side for the day, or vise versa.
The long ponytail through the back of the hatband is always a winner.
While I generally am drawn to longer hair on women there are some women who wear the short look very well. I saw a thread of you'rs where there were pictures of you with both long and short hair, you wear both well.
Change is good.
Some of us are not moved by the glam model types the print media, TV and Hollyweird would have us believe is THE only way to look.
Go with it, you sound like you're taking it very well and don't need my encouragment but I offer it anyway.
Oh, and we need pics!
