You can also decide according to your actual situation. If MM wants to wear a skirt to show her leg length, it will be very effective to buy a shorter skirt, then put the top into the skirt and match it with the leggings below. Slim and tall, black skirt works best. It is better to have a color at the bottom, and it will feel better with the style of black skirt, so the effect is obviously different.
You can just wear black leggings. If it is an ordinary skirt, it can be paired with all-black leggings. If it is lace or chiffon, it can also be paired with a little style of black leggings. If you are a little sexy, you can wear it with ripped leggings and patterned leggings, which will better match the skirt. I believe that such a combination will definitely become a beautiful girl in the eyes of boys.
