The slim cut is a classic style, gently tapered at the back and shorter at the sides to elongate the leg. Made from lycra fabric, it's stretchy, so sizing is flexible.
​There are two lengths, regular and longer
The best way to choose your size is to measure your child's waist. 
 The approximate lengths according to waist sizes. Longer length adds about  3cm all round.
