Iris is one of my favorite perfume notes, but some versions are arguably too earthy and deep for really hot weather, to say nothing of really hot humid weather. Here are five that won't overwhelm when the mercury climbs:
Prada's Infusion d'Iris: The gold standard for a summer iris perfume is probably Prada's light-as-air Infusion d'Iris, which many of us wear year-round. If even the gauzy Eau de Parfum is too much for you, you could try the lighter, more citrus-y Eau de Toilette, or the (soapier) masculine counterpart (which a woman could easily wear), Infusion d'Homme. (Note that Prada is revamping the Infusion line this year, so we'll have to wait and see which versions survive the cut. For now though, both the Eau de Toilette and the Infusion d'Homme can be easily found in stores.)
Penhaligon's Iris Prima: Iris Prima is as undemanding and easy to wear as Infusion d'Iris, but it's also more overtly 'pretty' than the Prada. It manages to stay in unisex territory, though, and if the Prada did not already exist, I probably would have loved it more than I did.
By Kilian's Prelude to Love: Moving up the price scale, Prelude to Love is another light-ish unisex iris. It does get earthy eventually, but the orange blossom and citrus are equal players in the mix, and they last long enough into the dry down to give Prelude to Love a summer-appropriate feel. I kvetched about the price when it launched, but now that you can find it in travel sizes I'm feeling a bit less cranky.
L'Occitane Iris Bleu & Iris Blanc: If they hadn't discontinued it, Crabtree & Evelyn Iris would be my pick for a simple but pretty, reasonably priced iris. Alas, it's gone. Iris Bleu & Iris Blanc isn't quite as reasonably priced, and it's too clean for me personally, but it makes a decent starter iris, especially if you like your fragrances clean. If you like clean and basic and want to spend more, you could try Aerin Iris Meadow, although I don't think it's as good as the L'Occitane.
Parfums DelRae Mythique: Like the Prada, a season-less 'veil of scent'. Angie described Mythique as "buttery iris and fresh, green suede with a breath of salt" AND as "leather chiffon underwear" — who can resist?
And do chime in — what are your picks for summer iris?
