Start with real-life use
Think about where you will wear it most: work, study, everyday outings or social events. A signature scent should fit your routine more than it should impress on paper.
Choose a style you consistently enjoy
Look at the scent families and notes you repeatedly like instead of buying a popular fragrance that does not match your taste.
Wear it more than once
Test the fragrance on several days and in different temperatures before making it your default. One first impression is not enough.
Check comfort after several hours
A fragrance can have a great opening but become tiring later. Make sure you also enjoy the middle and drydown.
Do not turn the idea into a rule
You can have one main fragrance and still use alternatives for seasons or occasions. The goal is identity and comfort, not wearing one bottle forever.
