You are not allowed to wear 90 yards of cotton-padded clothes and half-meter cloth. The child's 90-yard dress is 50 cm long, the bust is 50 cm, and the half-meter cloth is 50 cm long, which is not enough for cotton-padded clothes. Children's clothes are numbered differently from adult clothes according to S/M/L size groups, in which age size groups and height size groups are numbered directly according to age or height, and odd size groups or even size groups are numbered according to odd or even numbers. You can choose the appropriate size and fabric according to the corresponding relationship between single and double sizes and age and height.
