If I wear too much tartan, I tend to look like a Thermos flask.
All men look nerdy in black socks and sandals.
My weakness is wearing too much leopard print.
I've had a lot of tragic hairdos and outfits.
Never wear plaid.
I tried to pull off a pair of thigh-high suede boots once, but my legs just looked like two big trouts wrapped up.
Being trendy is alright, but clubbing all the trends in one look is a complete no.
Sometimes Italian fashion, especially in the summer, is bright and gaudy and tarty, so I'd be buying these bright pink and bright orange things, and when I got home, I'd just go, 'What was I thinking? I can't wear this!'
A guy's biggest style mistake is definitely trying to look too cool. As long as you've got a good pair of jeans, a good pair of boots and a few good shirts, you're fine.
