This designer makes some of the finest (and most expensive) leather shoes. Their bespoke service customizes every detail of the shoe, including their signature fiddle back waist. All this starts at about 2,500 Euros and requires at least two fittings in order to trace and measure, then do a refitting a month or two later.

But you will feel it in the quality of the shoe, made of some of the finest Florentine leather, with each pair accompanied by an antique sixpence silver coin placed in the box as good luck—drawing on an ancient Scottish tradition. But if you prefer footwear that is just a bit more casual, here are some High-End Sneakers That'll Floor Everyone.

The bespoke suit experience at this Italian tailor is as much engineering as artistry, where every element is customized—the fabric (windowpane, pinstripe, herringbone, or one of hundreds of exclusive fabrics), the style, and the stitching. Each suit takes at least 22 hours of craftsmanship to create, not to mention 6,000 handmade stitches. This attention to detail has caught the eye of plenty of Hollywood heavyweights, including Denzel Washington, Michael Fassbender, and Samuel L. Jackson.

This high-end shirtmaker has been creating bespoke shirts, ties, and pocket squares in Paris since 1838.

This designer, located in central London's Savile Row, embraces the street's tailoring heritage, by taking his bespoke service to the next level. William himself is involved at every stage, offering a hand-cut suit from a pattern he drafted, unique to the wearer's measurements. As he puts it: "A pair of trousers is made from 57 separate pieces. A jacket is made from 109. Not using standard shapes and block sizes as many do means your suit is made to fit you—not made, then made to fit. This gives your suit perfect shape."

This Italian design house has been "shoemaker to the stars" going back to the early 1900s, opening up The Hollywood Boot Shop back in 1923. Today, its signature Tramezza shoe is worn by the likes of Hugh Jackman, Jake Gyllenhaal, and Bradley Cooper. You can customize your own, selecting from three classic styles—the Oxford, the Monkstrap, or the Monkstrap Boot—and tailoring the material, color, buckle finish, and everything else to your particular taste.ae0fcc31ae342fd3a1346ebb1f342fcb

This designer, located in North Leeds, promises to dedicate no less than 75 hours to crafting a customized suit for clients, cutting and sewing it on site at his workroom.

And speaking of suits, one great way to up your suit style is with one of The Best New Blue Blazers for Men Right Now.

This Paris-based designer hand-makes shoes and suits to order, sweating every stitch. For shoes, that means bespoke treatment from the wooden last to the selection of leather and patinas. For its signature Grande Mesure suits, it means selecting from 3,000 fabrics woven by prestigious designers everywhere from Italy to Japan, with four appointments to ensure every piece is molded perfectly to the wearer.

The Made to Measure Suit is the pride of this legendary Italian designer. The fabric is sourced from Kiton's exclusive wool mill, Lanicificio Carlo Barbera, where the house creates its fabrics. Each suit draws on the traditions of ancient Neapolitan tailoring. Those looking to splurge can invest in the K50 model, created exclusively by five of the design house's tailors, that comes with a longer silhouette than other Kiton models, thus requiring twice as much time to create.

According to Vanity Fair: "Anderson & Sheppard is perhaps the finest bespoke tailor in Britain—which is to say in the world… [It] is the standard-bearer of Savile Row—tailors to Fred Astaire, Noël Coward, Gary Cooper, and the Prince of Wales, not to mention sundry dukes, barons, maharajas, marchesi, industrialists, actors, composers, Rothschilds, Guinnesses, and Waughs…." Need we say any more?
