You mean they don't hold up the trousers? I agree that the buckled type doesn't really work that well, but then neither do belts, unless you wear trousers at your natural waist. I've got a fitting for a pair of trousers with buttoned side tabs and hidden elastic tomorrow -- hopefully it'll work better.
As for not liking the look, well, that's an interesting departure from SF consensus. In Naples and in Italy generally they certainly like their belts. But I'm trending more and more towards the beltless look, and braces end up looking too pretentious more often than not.
