If your perfume has a stopper, do not apply it directly on the skin. The oils from your skin will go back into the bottle and could change the scent of the perfume. Store your dusting powder and puff in your lingerie drawer. The scent will gently lace your lingerie with fragrance. What you eat affects how you smell.
Fragrance rises rather than falls.
If you want to smell the scent you're wearing, be sure to apply it to more than behind your ears. Avoid wearing fragrance to the beach. It may increase photosensitivity. It will help them from deteriorating before there's been occasion enough to enjoy them. The next time you empty a perfume bottle, do not throw it away.
