Spraying a perfume in a shop rewards the top notes: the bright, light molecules that evaporate first. They're the ones in the advertising, and the least useful sign of whether you'll still like wearing it on a Thursday afternoon. A week of wear shows what the opening hides.
The seven-day test
Same amount, same pulse points, about the same time each morning. Note what happens at three hours, six hours and the end of the day. Don't reapply, or you're measuring your patience rather than the perfume.
| Day | What you're testing | What usually shows up |
|---|---|---|
| 1 | The opening | The loudest, brightest phase, and the easiest to be fooled by |
| 2 | The dry-down | Whether the tail end is smooth or harsh once the top notes go |
| 3 | How long it lasts | Hours until it sits close to the skin |
| 4 | Projection | Whether it reaches across a desk, a train or a classroom |
| 5 | Getting used to it | Whether you can still smell it on yourself, and whether you mind |
| 6 | Your skin | Any redness or irritation that repeats. If a scent bothers you, stop wearing it. |
| 7 | Whether you reach for it | Choosing it without being prompted is the only honest verdict |
Run it twice if you can, once in a warm week and once in a cool one. Heat changes how a scent behaves, so something that blooms in winter can be too much in an Australian summer, and a citrus that's perfect in January can vanish in July.
Four things that decide whether it lasts
Concentration. Extrait de parfum is the richest, eau de parfum sits in the middle, eau de toilette is the lightest. Treat any strength figure in a listing as a starting point, and let the week decide.
Projection. A scent can be excellent and still wrong for a shared office. Test it on a day you're around people. Fewer sprays usually fixes it better than a different bottle.
Dupes. An "inspired by" perfume is its own formula built to resemble a famous one. The difference usually shows in the dry-down rather than the opening, which is exactly what days two and three are for.
Batch changes. Two bottles of the same name can smell different if the formula changed between production runs. If a favourite smells thinner than it used to, that may be why. Keep your receipt.
Where a weak formula gives itself away
- A base that collapses within a few hours, leaving a faint sweetness and nothing else.
- An opening that smells sharp and alcoholic rather than blended.
- Sweetness that's pleasant at ten minutes and cloying by the second hour.
Checking a marketplace listing
| Look at | Worry if | Reassured if |
|---|---|---|
| The seller | A new account with no feedback | A long trading history and recent reviews |
| The listing | No size, concentration or batch detail | Concentration, volume and batch stated |
| The reviews | Uniform five-star praise posted in a short window | Mixed reviews that mention longevity and dry-down |
| Returns | No return path stated | Returns and refunds spelled out |
| The price | Far below every other seller for the same bottle | In line with the rest of the market |
Viral perfumes keep landing in Australia through ordinary shops now. Mecca, for example, has stocked the American brand Phlur since August 2025. So buying from an unknown overseas seller is less often the only way to get a trending scent than it used to be.
Sample, then scale
Most unused bottles were bought blind. If there's a travel size or a discovery set, start there and run the week on it. If there isn't, compare the scent to one you already own and like, and read the negative reviews for complaints about longevity and dry-down, since those are the flaws most likely to bother you by day five.
The limitation: a week on your skin tells you about your skin. Somebody else's week, including any review you read, is a different test.
