I believe women and girls have pressures to look beautiful and as thin as possible. Advertising is geared to thin and well proportioned model types. Women don't all fit into this mold and it can be detrimental to some. Many girls feel they have to uphold a certain image and always have to deal with guys attraction and advances. It's not easy being a girl or woman. I certainly don't envy women or girls since they have to put up with so much. That certainly explains why girls and women opt for the casual look sometimes. If you are a girl why would you want to wear a dress all the time? I can see why girls would resist wearing dresses? They want to get away from always being a lady and so feminine. Who can blame them!
Great point raised in your thread!
