I don’t want to picture Prince Charles lighting a Lily of the Valley candle and anointing his body with English Fern eau de toilette, but the fact is that Penhaligon’s, established in 1870, is listed as an official supplier to the Prince of Wales, so it may be happening right now. Penhaligon's hand-squeezes and custom designs its own fragrances for both men and women—generally floral-based and gentle—and sidelines in luxury shaving and grooming products. A picturesque location is at 16-17 Burlington Arcade (Tube: Green Park).
