We little girls need a pair of trousers and a sweater with a high waist to wear a coat. Wearing a white lapel trench coat, a gray sweater with a hat and a belly button, a pair of high-waisted black jeans and a pair of sports shoes or sneakers is the way to improve the waistline.
It is not recommended for girls to show their ankles in winter, but if they want to wear long legs, they need some high socks with solid colors, a loose bottoming shirt, a pair of high-waisted nine-point straight pants, canvas shoes, socks and shoes of the same color.
The third is simply to wear some high-top shoes, but not too high. You can wear some high heels in summer, a long skirt with a pair of high heels, and some padding in winter.
