Fun fact. I like a seasonal scent. And the more obvious the better. Lavender in the summer. Pine in the winter. Right now is prime Campfire! season. And I try to coordinate the smelly things in my house like diffusers and candles and dish soap. So I've compiled a list. Here, my friends, is Campfire!
Candle - Diptyque Feu de Bois (all you really need - nails it)
Kitchen soap - Caldrea Plum Bergamot Clove (Amazon sells it and it's amazing)
Perfume - Jo Malone Wild Fig and Cassis (the personal scent equivalent of Feu de Bois)
The Olsen twins just look like a campfire would smell. Smoky, wooly, slightly damp.
