Getting a leotard that fits properly and looks good is important to girls who take gymnastics lessons. Those which are too loose or too tight can give wedgies. Also it is distracting to wear a leotard that doesn’t fit right. A gymnast should be able to concentrate on what she is learning and practicing instead of on being uncomfortable from a bad fitting leotard.
The instructions in this video are helpful for selecting the right leotard. Keep in mind when ordering online that some brands of leotards run small for sizes that are common for girls. So a girl who wears size 4 clothes might need a size 5 leotard. If you order online and the leotard doesn’t fit right, return it for an exchange or a refund.
