Anthony, realizing that you live in the north of Europe I think the bigger question might be: will perfume x
be good in cooler weather, too? A warm day will always make your fragrance a little bigger, and sometimes brings out notes you haven't noticed before. French perfumes were originally developed in France and usually stand the warm weather test easily or have even been made for it. Joop's perfumes are relatively new and may have been targeted to a much wider market across the globe. Like always with perfume - be open to try yours under any condition, to find out it's best use.
I don't wear A'Men and Joop, because I somehow do not care for them. But I love to wear Antaeus occasionally. To me it's a 'black tie' kind of a fragrance (white shirt, evening affairs, Beethoven concert, etc...). These events are usually indoors, and it can be quite warm there, even at dinners, to the point of being uncomfortable. So I use such a fragrance sparingly. At such occasions the time of the year is irrelevant. My personal opinion: in Summer Antaeus palette seems to be much wider - like Lagerfelds fan!
I happen to prefer it that way, and I have had neither compliments nor complaints from others. That's just not a habit where I live.
