What are the benefits and limitations of purchasing a pair of jeans?
Benefits would be that good jeans last a long time and are pretty durable and rugged. Plus they look nice too. Only limitation I could see is how much you want to pay for good jeans but high price doesn't always mean high quality. You can wear a nice pair of jeans just about anywhere.
Benefit ... They fit better than a single jean
