     Department stores sell ready-to-wear clothing, which is also called ready-made-clothing Such clothing

is made in fixed sizes. Those people who find that ready-made clothing fits them well can save money by

buying it. Most often. People do not fit exactly into a producer's size. Their clothing must be altered (改变)

to make it fit better, However, most alterations are not very expensive. The small cost of most allerations

means that ready-made clothing can meet the needs of most customer.

     Those who can afford it often get someone to design and make their clothing. Such clothing is called

custom-made(定做的). The person who makes it measures the customer, and then sews it so that it fits

perfectly. Alterations are not needed. Custom-made clothing is largely sewn by hand. Has better quality,

better material, and is of the style you have chosen. Of course, it costs much more than ready-to-wear

clothing. You need to pay the difference for the special fitting and better skill that you are receiving. This

often means that you spend double or more than you would for a ready-made garment (衣服).

     Custom-made clothing is not always that much better than ready-made clothing. It costs more partly

because only one garment has been made, just for you. Companies that produce ready-made products make

thousands of garments at a time. This means they can buy large quantities of material. Workers cut each

size by the hundreds. Companies work out ways to make the garments, quickly ly machine and pay workers

according to their skill. Thus they can sell the finished products at a low price while still making money.

Most of the clothing sold in the United States is made in this way. Customers gain from the lower prices

which are made possible by mass production (批量生产).It may or may not give them high quality.
