Though a putative Roman style is, it turns out, a hard thing to quantify, inevitably all those eras collectively inform the way Romans put themselves together. Silvia Venturini Fendi, a scion of one of the city’s great fashion houses, has been known to patronise De Ritis, the famed purveyor of sacred vestments, to have a cape or coat made. Her daughter, the 38-year-old jewellery designer Delfina Delettrez, often favours themes of memento mori and reliquaries, the gilded macabre of baroque Rome, when creating her collections. “I look for traditions I can twist” is how she puts it.
