Performance basics
Does perfume performance change after delivery
An initial post-delivery impression is not enough to establish a permanent performance change. Check the correct item, packaging and application, then evaluate it under appropriate ordinary conditions without assuming a universal settling period.
A HUME Fragrance buying guide

Inspect the order first
Confirm the name, size and product condition. Keep order details and report leakage, damage or an incorrect item through the seller's actual support process.
Separate conditions from conclusions
Your first trial may differ from a previous experience in application or setting. Follow handling directions and use a clear repeat record before assigning a cause.
Avoid magic waiting claims
Do not assume every bottle improves after a fixed number of days or that deliberate airing is required. Seek product-specific information instead of improvising a treatment.
Try this before you buy
Record the received item, condition and first trial separately so an order issue is not confused with a scent preference.
