"The width of the hanger should not overpass the width of the shirt shoulders." —Anne-Marie Colban, who co-owns and operates Charvet , a shirt-making company.

Anne-Marie Colban, who co-owns and operates the legendary shirtmaking company Charvet , suggests these tips for taking care of your button-down shirts:

Pay Close Attention to the Insides of Collars. It’s here that stains can creep up from skin products, like lotion or makeup. Be sure to wash them immediately, especially before hanging shirts in the closet (scroll down for tips on how to remove stains).

Avoid Dryers. They will break down the fibers of the fabric and cause the garment to shrink and age prematurely.

Instead, Air-Dry on Hangers . Colban prefers wooden ones . “The width of the hanger should not overpass the width of the shirt shoulders. Make sure the shoulders are well laid on the hanger and more generally, pull a little bit the fabric of the shirt to limit wrinkles (this will facilitate ironing).” When storing hangers in the closet, she suggests leaving space between them — to keep the pressed shirts smooth.

Rewash Stains. “Before ironing, it is important to check that there are no more stains. If there are, wash the shirt again.”

Iron With Water. Colban advocates for steam or no steam, whatever you prefer, but cautions against completely dry ironing. “It is better to iron the shirt when it is still humid. If necessary, a spray with water can make ironing more easy.”

Iron in Order. The correct ironing order is: collar, cuffs and then the rest of the shirt, says Colban.

Pack Them Well. Before traveling with a dress shirt:

Button the shirt completely. Put a plastic or cardboard band — the kind that come inside new shirts from the store, or from the cleaners — inside the collar (to help support the collar and maintain its shape.) With the shirt front-side down, place a sheet of paper or tissue paper on the back of the shirt before folding it (to avoid creases). Use soft cases, like these , to keep the shirts in good condition. When piling the shirts, alternate their directions.

Insider Tip: Wrinkle-Free Traveling. “I travel with a small spray bottle, and then I fill it with water,” says Bruce Pask, Bergdorf Goodman’s men’s fashion director. “When I unpack, I just give the shirts a quick spritz and tug on the bottom of the hem, and then the wrinkles kind of come out naturally without needing to press it again.”
