I think hair length also varies in culturally. Some people think shoulders is long, that's why I think it's so important to stress how much length you want to cut off when going to a stylist. I went to an upscale salon with hair on my ****s, and I told the "master stylist/owner" that I wanted a trim, ONLY TAKE A BIT OFF, because I always wear my hair long. She cut it about an inch above my armpit. I didn't know this because she was cutting behind me the whole time! When i came out of there, I swear I wanted to cry!
