Sorry friends/family/girlfriends/colleagues, but men are more likely to heed the words of a movie character than they are you.
Let's face it, when it comes to taking advice, men are scientifically wired to observe the wisdom of someone they like, someone they trust, someone like say, a film character. Granted, they may be a mere figment of a scriptwriter's brain, but if they're always well turned out in tailored suits and polished brogues, odds are you'd be more inclined to adhere to their style guidance than Greg from Accounts who still wears a tie like a truant schoolboy.
And, for all the riveting storylines and gripping drama, it would appear that a great deal of cinema has been merely white noise for what's really being imparted on screen - subliminal fashion advice. So, feel free to absorb the sartorial wisdom of Messrs Brüno, Bateman and Burgundy (and plenty more that don't begin with B), as they present the best fashion lessons of cinema.
