Since the business debuted in 1986, its club-like membership grew primarily because of the shop's custom tailored clothes.  Their trademark smartness reflects my own thirty-odd years of prospecting at the hands of Europe's high priests of tailoring.    Today the "Flusser House Style" owes much of its sartorial pedigree to the London drape suit.  Popularized by the likes of England's Duke of Windsor and America's Fred Astaire during the incomparably stylish decade of the 1930's,  this Savile Row cut of the clothes formed the staging upon which the era's upper class male established a standard for masculine attire that has yet to be surpassed.      Like its fashion-breaking precursor, this "house" silhouette affords the wearer an athletically shaped torso and elongating leg line.  Handmade in luxurious English cloths, designed to drape and feel light on the body, once a man takes one out for a spin, the most understated of charcoal worsteds becomes something more than a simple gray suit.
