How to use a 50ml perfume bottle
Use a 50ml bottle through a deliberate routine based on the product directions and your setting. Bottle capacity alone cannot determine the right number of sprays or how long the purchase will last.
A HUME Fragrance buying guide

Confirm the favorite
Match the maker and version if moving from a sample. Similar names can describe different fragrances.
Reassess the atomizer
A full bottle may deliver differently from the trial vial. Do not assume equal spray counts are equal amounts.
Respect everyday proximity
Offices, transport and dining can call for restrained use or none. Extra volume is not a reason for extra presence.
Try this before you buy
Check sample-to-bottle identity and learn the selected bottle's applicator before repeating a sample routine.
