Why: I've always been wary of carrying small fragrance bottles in my purse, convinced they would inevitably open and stink up all of my belongings. But now, Marc by Marc Jacobs has premiered its Daisy perfume in the form of a charm necklace housing the fragrance in solid form. This works out well in my favor, since I happen to wear this scent anyway. The daisy pendant has a cheeky, retro feel to it, and it's simple enough to wear often. Even if you don't hang it around your neck, I would suggest sticking the necklace in your purse for that 5pm touch-up.
