单项选择题

When you want to go shopping and decide how much money you can spend for new clothes, think about the kind of 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 by washing in cold water. The label on a coat may say "dry clean only". Washing may ruin(毁坏) this coat. If you do as the directions say on the label, you can keep your clothes looking their best.
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-made. Well-made clothes last longer. They look good even after they have been washed many times. Clothes that cost more money are not always better made. They do not always fit better. Sometimes less expensive clothes look and fit better than more expensive clothes.

If you want to save money, you can buy clothes that need to be dry-cleaned.
[A] Right. [B] Wrong. [C] Doesn’t say.
