Mary Woodward for The Guardian on her shopping rules
It was an entire article, but these are my favorites:
1 - Don't take anyone with you. Especially not men and friends. They will have no stamina and won't concentrate properly.
2 - Don't let anyone make you think that shopping is morally undesirable. It's fashion, for heaven's sake, not landmines or ebola. If you have earned your money and are not letting dependent children or animals go cold and hungry then spend it on clothes if you choose to. You are not a less worthy woman for buying good clothes occasionally.
