If quality is defined by what one likes, then Cassie's Fragrance Boutique & Scent Bar is easily St. Louis' highest-quality perfumery. Cassie Buell, the store's sunny owner, began her career as a clerk in the '90s and has the chutzpah to fill her store with what she loves. She's also uncannily intuitive about what Central West End shoppers want such as an affordable "fragrance experience" of custom perfume-oil creation and designer-inspired perfume oils. Cassie carries a carefully thought-out selection of popular brands, including Burt's Bees, Boss Lady and Crabtree & Evelyn, but her best-selling product, Earthly Body's Suntouched line of soy candles, is new terrain. They do double duty as candle and warm massage oil a sexy concept enhanced by sweet, subtle fragrances. Simply put, an hour at Cassie's is a girlish treat you can afford to give yourself and your friends.
