Hi does anyone know where I can buy ds trousers that fit, it's driving me insane! He is 4 very petite his waistband hips are tiny. But also very tall his legs are very long. So length wise he needs length 5-6yrs but round the hips size 2 years. We have tried belts and braces with some success but he wants to wear not jogging bottom trousers and I can't find any that will stay up or not look like shorts. Any ideas pretty please ?
