[单项选择]Women’s fashions tend to change more rapidly than men’s. In the early 1900s all women wore their skirts down to the ankle. Today, skirt length varies from floor- length to ten inches above the knee. Women’s shoes have also gone through all sorts of changes in the last ninety years. For instance, boots for women were very common at the beginning of this century. Then, for a few years, they were not considered fashionable. Today they are back in style again in all colors, lengths, and materials. In fact, today’s women can wear all types of clothes, even T-shirts and shorts on almost any occasion. While all of these changes were taking place in women’s fashions, men’s clothing remained pretty much the same until a couple of years ago.
