Apply fragrance to your skin and pulse points only. Allow it to dry naturally. Do not rub your wrists together, this will alter and diminish the scent. Avoid using it near your face or behind your ears. There is no staying power in those locations and this will only dry out your skin.
To avoid any stains and discoloration, do not get any on your clothing or jewelry. Let your fragrance dry before getting dressed. Some perfumes are darker and have more of a tendency to stain, so take special care with "dry clean only" clothing that can't be washed after every wear. Follow proper storage rules, fragrance will darken with age and improper storage.
For a longer staying aroma, apply the same scent in layers. Many fragrances also come in bath soap, gel, and body lotion. Top off with perfume of the same scent for the long run. This will probably last you 6-8 hours.
Keep strong fragrances out of the office and workplace. Some people genuinely have an allergy to perfumes and don't appreciate the irritation. They can produce headaches and bring on an asthma attack, so apply sparingly.
