Guys, I'm sure most if not all of you saw some 20's-30's girls walking on the street with their arms crossed. I tend to notice this alot and find it fascinating and puzzling at the same time. It can't be to keep them warm because they do this in warm summer days too. I've heard alot of theories about this, everything from them not feeling comfortable with their breasts shape/size and trying to hide it, trying to reduce the 'bounce' when walking, wanting to give a 'stay away' message, to being introvert/insecure or feeling threatened. They also tend to look at the ground right in front of them when walking like this.
Why do you think they do it? This is something you never see guys doing lol.
For all the girls here, if you do this (that is, if you're aware you do it) please chime in and give us some pointers to try and solve this perplexing mystery.
