1 ml, 2 ml or 5 ml: which perfume sample size should you buy?

Short answer: Buy 1 ml to find out if you like a scent at all, 2 ml when you are seriously considering a full bottle, and 5 ml when you love it but would wear it fewer than about 20 times a year.

The short version: 1 ml answers "do I like it?", 2 ml answers "should I buy the bottle?", and 5 ml is often the only size you need for a scent you save for special occasions.

What samples cost

From 58 sample listings across the niche and luxury fragrances in our library, checked Nov 14, 2026:

Per ml, larger samples are a little cheaper, but not by much: the big saving only arrives with a full bottle, where the median in-stock listing in our library is about $3.90 per ml.

How to choose (a dating metaphor, because of course)

1. 1 ml is a first date: is there a vibe? Buy it when you are curious, or testing five scents at once to find a direction. Two or three wears.

2. 2 ml for anything you might buy at $150 or more. Four to six wears is enough to judge longevity and the drydown in different weather.

3. 5 ml when you love a scent but $250 to $400 is a lot for something you'd wear twice a month. Ten to fifteen wears can last a year.

4. Skip samples and buy the bottle only when you have already worn the scent several times, for example from a friend's bottle or a store tester over several days.

A worked example: Baccarat Rouge 540

At Fragrances Line on Nov 14: 1 ml $9.99, 2 ml $18.99, 5 ml $41.99. The same shop listed the 70 ml bottle at $270 ($3.86 per ml), though it was sold out. If you would wear it once a week, the bottle is the better buy within a few months. If you'd wear it ten times a year, a 5 ml decant covers you for about a year at a sixth of the price. All BR540 prices.
