There have been times, in the heat of the summer, that I've been tempted to get my own hair cut short. But then someone in public squeals, "Ooh, I love your hair!", and I love it when that happens :-)

A few of my "real life" friends have very short, or even completely-shaved-off, hair (or they cut it all off at the beginning of summer, and let it grow out all year), for convenience and comfort, and it is an interesting "look", especially on someone you wouldn't expect! As long as you're comfortable with it, both physically and aesthetically, that's what matters. (Although I'm tempted to make or find a propeller beanie for you...)
