My one quarter ounce of toilet water had never been opened.
It is quite strong and true as a soliflore, almost parfum strength. Silghtly sweet and light, as opposed to the heavier scent of purple lilac.
The scent of lilac has almost gone out of favor. Very few perfumes created after 1950 featured this as a soliflore, although Basenotes does provide a list of half a dozen or so niche houses who currently offer scents with white lilac center stage.
Old-fashioned, comforting, truly lovely and feminine. Mary Chess' version is among the best I have experienced.
