It takes constant vigilance to keep tailored clothing looking as good as that worn by the late John Russell, the 13th Duke of Bedford and one of the best dressed men of the twentieth century in the opinion of Vanity Fair magazine.
Once a wool garment is worn, it should be stored on a shaped or padded hanger to rest for at least 24 hours (for worsteds; flannels and tweeds should rest for at least two days). Give it a good brushing, empty the pockets, remove belts and hang with closures zipped or buttoned. Many wrinkles that developed during the wear will fall out of their own accord overnight.
Before wearing the garment the next time, remove remaining wrinkles, and any new ones that developed during storage, with a steamer. Steam relaxes the fibers and, unlike ironing, will not scorch them.
Founded in 1940, Jiffy Steamer is the oldest U.S. manufacturer of steaming equipment for wrinkle removal. According to the company, Jiffy manufactures over 16 fabric steamers and clothes steamer models.
The Jiffy J-2000M Steamer ($189 from the company) is the model the company recommends for home use on clothing. I have one at home and it wipes wrinkles away quickly and easily with a continuous flow of steam. I also pack Jiffy's Esteam travel steamer ($69 from the company) when I'm going on the road. It weighs a few pounds but is much more effective than the irons found in even the best hotels. Turning on the shower in order to fill the bathroom with steam has never successfully removed clothing wrinkles for me and frankly it bothers me to use so much water for so little reward.
