'When in Rome' was our motto last week when we were in San Francisco for meetings. Coutorture then, on our last day in the city, dropped some cash at the Sephora flagship. The single greatest find? Heatwave. One of us picked up the last one at Sephora which prompted the team to go in search of a second, so we walked all the way over to Nordstorm and there scored their last tube. Looks like this lipstick is a must-have for many, and we completely understand why. Dare we say it, it's the perfect orange lipstick. Apply the lipstick without gloss and with a bare, nude face (one of us tried on orange eyeshadow at the same time and were told we looked a little too neo sci fi) and you're good to go. We already wrote about orange nail polish, and now that we've hit our stride with this must-have summer beauty color, we're fully endorsing the lips. We declare Nars Heatwave the color of the summer.
