Like clothing, different scents go best under different circumstances. With two distinct blends, these C.O. Bigelow Elixir Colognes let you pick the one that best suits the mood. No. 1581 Black is a rich blend of agarwood, tonka bean, amber, and musk for an exotic vibe that suits formal affairs well. No. 1580 Blue, meanwhile, is a lighter scent with notes of lavender, rosemary, and white musk atop a woodsy base that's perfect for sunny days and warmer nights. Both arrive in handsome spray bottles.
