That site looks good, but putthison.com is the best site I know to learn about how things should fit etc. (and I know a lot of these sites…) - effortless gent links to them in many of their articles, actually. Often if you’re unclear on a certain thing you have to look at articles on several different sites, of course.
Both of these sites tend towards more classic fit and style - which suits James Bond well, even the trendy-ish stuff Daniel craig wears - for more current fashion there are of course many other sites to check, but I think starting on sites like these is the best idea.
