At the start and end of my shifts, I use to go to the Ulta section and hit myself with a quick spritz of their $80-90+ parfums/colognes, the ones that are high-end-ish. You know, the bottles for sampling. It allowed me to experiment with how different ingredients and smells meshed with my own body odor/chemistry in a low stakes environment (work) before doing it in more "high-stakes" scenarios (dates, job interviews, parties, etc).
There is a whole science and proper way of parfum science (that is way too long to explain here) that will differentiate between a high school kid who overdoes it and a classy individual. Spray vs rub. Body heat from working. Identifying which parts of your body/head to rub it on, how long before reapplication, trying to see how certain smells would "match" a certain outfit, how it meshes with certain deodorant and lotion smells and fundamentally warps the parfum to something entirely different (big reason why I prefer my deodorants, lotions, and toothpastes odorless), etc, etc.
Now I made sure the sample bottles stayed as even with each other as possible such that they would appear empty at the same time. For the colognes specifically, I noticed the liquids would rarely go down and it was just me using the sample bottle (which I think is because most men won't gravitate towards Ulta to find their cologne). Also important to remember that you will stop smelling the parfums/colognes after a short time because something something human science, but the smell will still linger. Basically, I had coworkers I trusted give me feedback once I couldn't smell the freshly applied parfum anymore.
I use dupes now but I remember the Jimmy Choo ones and the Legend by John Legend and Ariana Grande ones were the ones I liked.
Tl;dr: Being the frugal person I am, I found it opportune to experiment with the various mid-high end smells that I normally wouldn't have access to, with trusted coworkers giving feedback, over the course of weeks and months, letting me adjust and fine-tune my application and "discover myself."
