...college? I've seen this happen here before. Some girls or women have a trend of putting on a T-shirt with short sleeves and rolling them up all the way to the shoulders all the way through high school, regardless of how short the sleeves are and outdoor temperature. Also some of them wait until they almost turn 20 years old to finally stop this. How come? Is it true that it also applies to short-sleeved tops that fit the body perfectly and the sleeves are tight?
