The denser the lines, the higher and thinner they are. On the contrary, the fewer horizontal lines, the thinner and fatter they are. We can see the visual size of different numbers of horizontal stripes. To sum up, short girls had better choose clothes with horizontal lines, which are denser and taller. The fewer vertical lines, the taller and thinner you look. On the contrary, the more vertical lines, the fatter they look. Different numbers of vertical stripes give people visual dimensions. From this, we can draw a conclusion that it is better for short girls to choose fewer vertical stripes.
