When you want to go shopping, you’d better decide how much money you can spend on new clothes.

Think about the kind of clothes you really need. Then look for those clothes you really need. Then look for those clothes on sale.

There are labels(标签) inside all new clothes. The labels tell you how to take care of your clothes. The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash in cold water. The label on a coat may say “dry clean only”, for washing may ruin this coat. If you do as the directions(说明) on the label, you can keep your clothes looking their best for a long time.

Many clothes today must be dry cleaned. Dry cleaning is expensive. When buying new clothes, check to see if they will need to be dry cleaned. You will save money if you buy clothes that can be washed.

You can save money if you buy clothes that are well done. Well-made clothes last longer. They look good even after they have been washed many times.
