According to the books of etiquette, a suit should be chosen on the basis of the occasion. For more formal events, the type of clothing requested is indicated on the invitation according to the dress code. Together, the dress code for men and etiquette make up the unwritten rules to define elegance and which arise from the culture revolving around the sartorial suit. In The Bingley collections, Drapers proposes one of the widest selections of fabrics for every occasion, ranging from the more formal which require the Tuxedo or the black lounge Suit to those less formal ones where a classic suit can be worn. The selection comprises versions of the dinner jacket revisited in camouflage-effect jacquards, a Barathea for impeccable smoking jackets and the exquisite Doppione or Shantung in pure silk, a gem for the true connoisseur.
