What is it? An eau de toilette, developed by Comme des Garcons for the Serpentine Gallery (yes, that conjunction of facts didn't really compute in my mind, either, but here it is), which goes on sale on Monday 28th April. Does that make it a whole new brand? Not really but sort of, and I thought it needed a mention. What does it smell like? This is what it says on the website: 'a fresh, light, yet deceivingly complex, unisex scent composed of grass, leaves, pollen (galbanum, iris leaf), oxygene (aldehyde, ozone), asphalt (black musks, nutmeg), labdanum and smoked cedar with a little bit of pollution (benzoin, juniper wood, gaïac wood).'
