The staple of everyone's wardrobe. There is a statistic that states that at any given time most people have at least eight pairs of jeans in their closet. Living and working in Los Angeles offers the option of going to work in jeans. I know that I am one of the people listed in that statistic. I have several different brands of jeans but here are the ones that I have found to be most useful. When choosing a pair of jeans you should be able to find a few pairs of everyday jeans that go with pretty much anything and can be used for most occasions. Also you are going to want a few pairs that are slightly more dressy for the nicer occasions and for more upscale bars and clubs.
For your everyday pairs I would recommend Abercrombie & Fitch. They tend to carry stylish jeans and have several choices in cut for your particular build and personal style. They have many different colors and washes in each cut of jean and can generally outfit anyone's taste. Their jeans are reasonably priced and can be matched with most clothes and shoes.
As far as dressy jeans go there are many choices. I am always wary of buying jeans that come from companies who don't specialize in jeans. Some of the choices that I would recommend are Diesel, Seven and Ben Sherman. These jeans tend to be more expensive and will probably run in the neighborhood of $200 a pair. Since these are nicer brands they are worth the money but make sure to try on several different designers before you make you choice. Once you have a pair of jeans that you like make sure that they will work with your wardrobe before buying them. If you are going to spend a lot on one pair of jeans you want to make sure they work with a lot of your wardrobe and will be worn often.
