As louise said it depends where u shop! I've never had a problem getting clothes to fit other than next trousers.we tend to go for trousers from tesco, sainsburys or asda and even their jeans fit great over our cloth.
Result - I stuffed a nappy with a prefold, 3.5 hours later and no leak!!!! The used another mf insert and Im just off to change him as it's leaked!! I will be selling all the mf inserts soon!!
