You know - there's a shop opened up around the corner from me and Mr Noodle-bob, selling "extreme wear". Now, correct me if I'm wrong, but t shirts are not extreme wear.

Diamanté underpants are extreme wear.
Dresses made of oxtail soup or butterfly wings are extreme wear.
Sunglasses made from real sun are extreme wear.

Yellow t shirts with company slogans on are merely gaudy.
