That was one of the hardest decisions for me when I went from having hair down to my ass to right at my shoulders. But I was tired of waking up every night every time I rolled over cause it got stuck under me, and its so flipping hot in the summer. and dried out on the ends. I love it, course your hair is probably about the length mine is now.
I almost cut it about 50 times before I finally got MadHatter to do it. You can always change your mind and cut it later.
