"As (silk) top hats are no longer in production, there is an infinite number in circulation and as such they are considered an investment piece," Oliver Brown proprietor, Kristian Robson, told CNBC over email.
"Therefore it's certainly worth investing as they will not lose their value and there is nothing like the elegant shine of a real vintage silk topper."
While renting has become increasingly popular, Berkshire-based Ascot Top Hats prefers to sell. Its owner Douglas Simpson told CNBC he usually sells top hats—ranging from £100 wool felt to £500-plus Silk Plush—to make sure customers leave with a hat that fits comfortably to their own head shape — which varies from person-to-person, while the hats have a specific structure that needs re-conforming.
"I believe selling is better than renting as you don't have to return the hat, also you also have the additional optional service of having the hat fitted (conformed to your head shape) to make it more comfortable," Douglas Simpson, owner at Ascot Top Hats, told CNBC over email.
"The top hat is the pinnacle of elegance, a silk plush top hat embodies the traditions old, the necessity for a gentleman wardrobe, and aim to put one head and shoulders above the rest."
