You don’t have to be rich to have a great fragrance wardrobe. You just have to learn what you like, and then budget accordingly.
There are a lot of places online that will sell decants (small samples from a larger bottle) for a small fee. This is a good way to try things that you don’t have normal exposure to without doing a ‘blind buy’ on a full size bottle. Google for decants or scent splits and have a field day!
Scentsplit, Luckyscent, Fragrancesplit, Decantx, Microperfumes and others sell samples. Many will give a coupon for x% off a full bottle purchase thereafter.
Some fragrance houses also sell sample packs of their scents or will make travel size packs for a little more, such as MFK, Killian, Zoologist, Mancerra, etc.
If you live in a large metropolitan area, you may be able to take advantage of a good size retail establishment and try on samples there for nothing but a conversation with a friendly sales agent.
Have fun out there!
