MALIN + GOETZ DARK RUM FRAGRANCE OIL Why you'll love it: If dark and stormies remind you of summer nights, this perfume oil with its notes of rum, sweet plum, and bright bergamot will be a nostalgic hit. It's inspired by that classic sailors' favorite-bay rum-with a sweetly crisp finish that makes the overall effect sparkling, not boozy. How you'll use it: Run the perfume oil over your pulse points (wrists, neck, even the back of your knees) for a breezy summer fragrance. "This oil' leathery-sweet fragrance lasts all day, even in the summer heat."
