When we wear clothes, they usually have a straight edge at the bottom and don't move around too much when we walk or run. But some clothes have a special design called a swallow-tailed hem. It looks like the bottom of a bird's tail with two points that stick out. This design makes the clothes look fancier and more special.
Flying ribbons are another feature that some clothes have. They are long pieces of fabric that hang down from the sleeves or back of the clothes. When we move around, the ribbons "fly" in the air, almost like they are dancing or playing. Flying ribbons are also designed to make the clothes look more interesting and beautiful.
So when we wear clothes with swallow-tailed hems and flying ribbons, we look extra cool and stylish because our clothes are fancier and more eye-catching.
