I am a sucker for iris. Any recommendations from the main collection? There are so many to choose from, I've never known where to start.

As a fellow Iris fan, 302 is one of my favorite fragrances on earth. I also really like 701, 702, and 902 which are all interesting and spicy! 401 is really nice around the holidays if you like that sort of thing. Their discovery set is super-budget-friendly and how I got hooked :).
