Because manufacturers certainly think so. Dd (9) wants some denim or cord or canvas dungarees as ds has some and she's envious, but I CAN'T FIND ANY!
Does no one make young girls' dungarees now? Dd hates playsuits/jumpsuits, oddly, but is desperate for a nice pair of dungareerees... The only ones we can find are the type for skiiing, padded waterproof jobs.
