We (germany) have them and they are quite often true to size. But many brands start with 25 or 26 inches, so no skinny shitlady sizes... I wear a size 24 which is still available in quite a few brands but everything below is almost impossible to get. And it is only jeans that come in inch sizes, somehow every other kind of pants (or skirts) don't... Last time shopping I found the most miss sized jeans, it was labled as a 24 but my best friend who has very big muscular legs and usually wears a 27 could easily put them on...
