I always thoroughly sample fragrances before committing to a full bottle. I often buy the travel size when available like Malle or Hermes or try to score samples of what I'm interested in when I do make a purchase (I sure miss when Malle was generous with those 3.5ml samples!!).
I don't think I have ever bought a fragrance without having at least a take home sample that I can wear several times. Testing on skin in store is just never enough for me to determine if I want a whole bottle of something.
but...
With this approach I lose some of the magic and excitement of buying a bottle. It almost feels like a chore to go ahead and buy the full bottle. Like buying underwear, I like it, I know I'll use it, but I'm already so familiar with it that when I finally purchase the bottle it isn't all that exciting.
This is not to say I regret any of my purchases, the upside is I love every single bottle I have. I suppose there is a delayed gratification in this approach, while the initial high of getting something new is diminished, I still appreciate owning the fragrance and having it to wear over and over.
Still, I can see the potential thrill in blind buying, smelling a fragrance and getting to know it for the first time when the bottle arrives must feel great (and sometimes horrifying).
Anyway, just some thoughts I had and curious if anyone else feels the same. What's your approach to "try before you buy" and how much do you test out a fragrance before getting the full bottle?
