Dry skin cuts down on the amount of time your fragrance sticks around. First apply some unscented oil (like jojoba oil) or a matching scented lotion or oil, wait a bit, then apply your fragrance. A tip for spraying: go for the back of the neck, particularly if you have long hair. (This is better for your hair than spraying alcohol-based fragrances directly on it.) Finally, to keep your fragrances from going bad on you for as long as possible, store them in a dark, dry, cool place (not in the bathroom), and consider keeping them in the boxes they came in.
