Jour d'Hermès is girlish but sophisticated. It's an ebullient floral bourrée at a time when flowers in perfume are sneered at by the young 'uns. Or seem only to be allowed smuggled under the cover of grit and oud, sheep-in-wolf's-clothing style.
But like a resolute posy pressing through a crack in the sidewalk, Jour d'Hermès asserts its right to unabashed floweriness. It's pretty and that's enough.
