Buy your motor oil and other auto supplies from a discount store. Prices are well below those at a service station. Don't buy clothes that require expensive care. Avoid whites, pleats and dry-clean only items. Hem your own pants and skirts.
Heat deteriorates hosiery and misshapes bras, so air-dry whenever possible.
Reinforce buttons on coats and jackets with heavy-duty thread before they fall off. Spray leather and suede shoes and purses with waterproofing to preserve and protect them. Redye navy and black cotton T-shirts and turtlenecks in good shape when they start to fade. You'll be able to stretch a few more seasons out of them. Carry a small bottle of clear nail polish to stop hosiery runs when they occur.
