The market for collectible or "vintage" clothing is born of a quixotic sort of persuit that is attracts a variety of followers. After all, just who really wants to buy somebody else's old shirts, dresses or jeans? The answer is, apparently, a lot of people from all walks of life and the prices of the garments sought after by these aficionados can be stratospheric. As in a black velvet evening jacket from Schiaparell from 1939 that sold at a Christie's auction in 2013 for over $75,000!
There are sub-groups in vintage clothing followers. Levis jeans had a collector-following for pairs of the pants that had a capital "E" in the word "Levis" on the back patch above the right rear pocket. Simply called "Big E Levis" a pair could fetch hundreds of dollars or even more. Though they are not really clothing, old tennis shoes have a very active market in collectors. Those old, original Air Jordan's can find buyers in the multiple hundreds or even thousands of dollars. A recent perusal of eBay listings showed one pair of "Airs" (a rare sample) priced at around $5000 and, if you are lucky enough to find yourself in possession of an actual pair worn by Michael Jordan in a game, you have the "holy grail" of sneaker collectors and its worth can only be found at auction.
But, back to clothing and the collectors of same. When we use the word "vintage" we are generally referring to an item that is at least 25 years old. In today's market, that would be pre-1990. People tend to collect by category or era, There are people that specialize in particular designers, Coco Chanel, Yves St. Laurent and Oleg Cassini come to mind, though many others have their set of followers and others that specialize in time-periods. Each decade from the 20's through the 60's has its share of fans. Vintage western wear is liked by many and the tie-dyed and colorful dress of the 60's hippies has many adherents.
One particular category that is, and has been, strong for years and that is vintage Hawaiian wear, old muu-muus, swimwear and, particularly aloha shirts have found a fertile collector following. Shirts that were produced from the thirties onward are coveted by collectors, particularly, says David Bailey of Bailey's antiques and aloha shirts, those of The Kamehameha Garment Company, which can, and have, brought sell prices of up to $5000 at his Honolulu store. This store is known to collectors the world over and is a must-visit for many Japanese tourists when they take their Hawaii vacations. Celebrities, such as Nicholas Cage have been known to drop thousands at Bailkey's in a single visit. Surfers also favor the vintage versions of this Hawaiian fashion staple, as they lend an authentic Island flavor to their apparel choice not generally available in the modern, mass-produced versions of same.
There are even collector websites that will value that which you own and might be willing to part with at a particular price. Vintage Vixen is one such site and there are others. Google vintage clothing and have at it. Who knows, maybe a fortune lurks in the back reaches of your closet??
