I have a plan for my perfumes but I think it's a bit odd. This is to combine popular fragrances from the last several decades. IDK if it works. Still want to buy a few. All at once would probably be a bit much lol.
These are a couple that particularly work-
Britney and Chanel No.5 -daytime
Chanel No. 5 and Poison- night.
Have you tried combining some and what were your results?
