I've had a couple of attempts at buying joggers for DD and they're just too gappy on the waist. Looking at the Next size guide she would need the waist size for age 5-6 and length for age 9 to get something that fits. Even their slim fit waist is still a few centimetres too big.
Does anywhere do proper adjustable waist joggers with the elastic/button system on the waistband rather than just drawstring?
