Don't let the retro packaging fool you: Eva is one of the newer fragrance releases from Santa Maria Novella. It came out in 2002, and has notes of citrus fruits, Italian bergamot, black pepper and vetiver.
There is nothing much to Eva; it is a simple unisex rendition of a traditional citrus-based cologne water, but very nicely done. It starts with crisp, dry citrus, and quickly takes on a nicely dusty pepper note, mingled, I would guess, with some other spice notes that I can't identify. It settles into pale dry woods underscored with earthy (but not overly so) vetiver.
That is the whole story, but it is probably just the right amount of a story for a hot summer day when you need something crisp and light and dry, something along the lines of Acqua di Parma Colonia or Hierbas de Ibiza, maybe, but not quite so sharp or herbal. Perfume Posse included Eva in their Best of 2005 fragrance list, noting that it "feels like fresh meadows and hay and outdoors and young love and a roadster heading south from Firenze". I'm not having quite that kind of a day so far, but hey, I can hardly blame the Eva.
Eva is available in 60 ml spray ($65) or 250 ml splash ($160) bottles of Eau de Cologne. For buying information, see the listing for Santa Maria Novella under Perfume Houses.
