I picked up a copy of Esquire at the airport and had a good laugh reading the following in Ask Nick Sullivan (‘The Esquire fashion director goes the extra mile to answer your questions):
Q: I work at home, so I wear pajamas all day long, and when I leave the house, I find wearing pants confining. Could you recommend some pant that approximate the relaxed freedom of pajamas? – Gabriel Lichstein, LA, California
A: No, Gabriel. No, I cannot. Put on some grown-up clothes and you just might find that being properly dressed focuses your mind. Or try a kilt.
I think Homer Simpson had the same problem.
