The best suit I've ever bought - style and fit wise - was an H&M special. Which is annoying as it's aged badly because it's so cheap. But it also goes to show that it's not about cost, it's about cut. Although it's kinda about cost so the suit doesn't turn into shiny, tracing paper within a month.
So tell me where you go for suits. Gimmie rough costs too.
