I've got a couple of pairs of khakis (RLPL and Hackett) that both fit like formal trousers. OK with nice shoes, shirt, jacket etc, but they don't look so good in dressed-down or 'youthful' (hem, hem) mode. Any recommendations or ideas for khakis/chinos that would work in these latter situations? Reasonably slim-fitting and available in the UK. Maybe cut more like jeans than trousers...? Thanks, F.
