Cotton poplin: There’s no easy way around a workday button-down. It’s best pressed with an iron (and even a little spray starch). Using a medium-high heat, start with the collars, cuffs and sleeves before moving on to the body. Finish by sliding the tip of the iron between the buttons.
Linen: This natural fiber crumples at the slightest touch and requires heavy-duty heat to get out any creases. Use the highest heat setting and a little elbow grease. Just make sure to immediately smooth over any dribbles of water (from the steamer tank) so you aren’t left with water stains. (It’s true--linen holds spots.)
Denim, chambray or khaki: This goes for jeans, pants, skirts, jackets, tops, anything. Because these sturdy fabrics (usually pure cotton) can withstand high heat, it’s easy to take an iron to them to quickly remove any residual wrinkles from the dryer cycle. But if they have touches of Lycra in the mix, beware of burning. In that case, a close steam it is.
