I test out a lot of fragrances, but only a few find their way into my refrigerator. (Sidebar: One time one of the perfumers from Le Labo, who happens to be very cute and charismatic, told me I should store all my perfumes in the fridge and I've done it ever since. It's next to the yogurt.)
I discovered Jour d'Hermès a few weeks ago when it launched and it's what I've been wearing every single day since. It's described as a delicate floral, but it smells crisper and more citrus-y to me. The scent lasts all day, and it's classy and expensive smelling, but still subtle. Much like a Birkin, right? But you can't get a Birkin for less then $150! (Also the bottle is impressively heavy--not great for travel, but fantastic for showing off on your dresser.)
