A common sight in Hanoi is a young girl or an old lady carrying two racks full of clothes, baskets loaded with womens' accessories or shoes. They look like a strange walking clothes shop. This kind of business is very popular in the north, not in the south. You always have to bargain for these goods and quality can also be a problem.
Most people who operate these mobile businesses are from the countryside. Their daily profit is about 30,000Vnd, not much for an 18 hour day. They walk along almost every street, meet lots of difficult customers but they still try to keep this business because this is their daily means of support.
Plastic shoes cost about 6000Vnd, clothes cost about 20,000Vnd per item. Quite cheap but remember, "you get what you pay for."
