As boutiques go, Conservatrice is one of those girly-girl pampering places where a gentleman might buy a gift for his lady love — or the lady herself might go for a moment's respite from the spinning world, among lace and linen, fancy perfume bottles, tinctures and lotions and, to top it all off, redolent floral arrangements perfect for prettying up a boudoir or a wedding reception.
