Diptyque is famous for its candles and eaux de toilette in sophisticated scents like myrrh, fig tree, and verbena (these are not inexpensive; the candles, for instance, cost nearly $1 per hour of burn time). The vinegar water can do triple duty, as an after-shave splash, a hair rinse, and, if steamed, as a room purifier. Métro: Maubert Mutualité.
