Clothes are important and necessary to us, but do you know how to choose suitable clothes in a correct way? Here are some ideas for you.

When you go shopping and want to buy some clothes,you should think about which kind of clothes you really need and decide how much money you can spend on them.Then look at the labels that are inside the new clothes. They tell you how to take care of the clothes.The label for a shirt may tell you to wash it in warm water. A sweater label may tell you to wash it in cold water. The label on a coat may say “dry clean only” and cleaning in water may ruin 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, you had better check if they need to be dry-cleaned. You can save money if you buy clothes that can be washed or that are well-made. Well-made clothes last longer. They look good even after they have been washed many times.
