Antique dresses, vintage tee shirts, and retro clothing tend to have high resale values which increase over time. Before you shop, however, let's go over some commonsense rules for creating and maintaining a modern wardrobe. First of all, remember the cardinal rule of ''less is more.'' Instead of buying four pairs of jeans at $40 each, you might want to buy one high-quality pair of jeans for $120. Try to purchase outfits as ''one of a piece,'' and be aware of color coordination as you shop.

Oftentimes, we are unaware of the eccentricities and defects of our own wardrobes. Seek out friends and colleagues who have good fashion sense and ask them frankly to evaluate your wardrobe. Purchase clothes which make sense for your profession. Professors may not need a full line of slick, modern suits, and investment bankers may not want to stock up on tweed jackets.

In addition, you'll want to get fitted, know your sizes, and try on all major purchases before you buy. There is an exception to this ''try on'' rule, however. If you know your size, you may purchase clothes through reputable online retailers.

Don't worry about compiling a great wardrobe all at once. If you don't have the money, it's better to compile your wardrobe piece by piece than to splurge on a mess of cheap and uncomfortable clothes. Caring for your wardrobe is also critical. Dry clean clothes that require extra care, and don't over-wash shirts, sweaters, and pants. Get good drawers, hangers, and closet space for your wardrobe, and take the time to fold your laundry right after the dryer finishes. Never underestimate the power of a lint roller to tidy up a sweater. Finally, don't be afraid to give away old clothes that don't fit or wear well anymore.
