Double black shorts. Prefect modern shorts for training in Rhythmic Gymnastics. Shorts with discrete black pants inside/underneath which means gymnasts protect their modesty when training. 
 
SEE SIZE CHART IN IMAGES - These shorts tend to come up smaller, so I woudl recommend going up a size.
 
Double Solo shorts with side cuts and a robust wide waistband band. Upper free shorts are made of polyester, lower tight-fitting shorts are made of cotton with the addition of elastane.
 
Shorts have a wide soft belt with elastic band for better fixation. Specialised professional shorts for rhythmic gymnastics, dance and ballet.
