Wear-time comparisons
How long do sweet perfumes last on skin
Sweetness is an impression rather than a duration rating. A sweet perfume may change in warmth or texture during wear, and the exact composition matters more than assuming every dessert-like fragrance lasts a fixed number of hours.
A HUME Fragrance buying guide

Describe the sweetness
Vanilla-like warmth, sugary fruit and other associations can feel different. Identify the quality you want to track rather than treating sweet as one material.
Record later enjoyment
A remaining sweet trace is not automatically a benefit if you dislike the later balance. Preference should be logged alongside detectability.
Avoid a strength shortcut
A prominent opening does not prove long-lasting surrounding presence. Compare the later close-range impression and projection as separate observations.
Try this before you buy
At each observation, record sweetness balance and whether you still want to wear the scent.
