Reddit mentions of Issey Miyake L'eau D'issey Eau de Toilette Spray for Men, 4.2 Ounce

That's a mighty big question there. I won't go into department store brands, as you should really just swing by the fragrance counter at any store and try them. So here are some ones that I personally like that definitely don't break the bank. I stuck to my summer scents, but there's no rules about what you can wear or when.

I would highly suggest researching any suggestion that sounds good to you a bit more on forums like Basenotes just to see what others say, as you always want at least a second opinion before you blind buy anything. If you feel like just trying out a bunch of scents, there are good decant (bigger than samples) sites like Surrender to Chance or The Perfumed Court where you can get 3,5,8mL samples that will last quite a solid amount of time. Long enough to really get a feel for a fragrance as it works on you. It's not a cheaper way to do fragrances, as you're paying for convenience. But, since your only other option is a few whiffs at a department store or a blind buy, there's some good reason to pay the premium.

I'm terrified to recommend blind buys, but if there was ever a low-risk/high-reward ratio winner, it would be : L'Eau D'issey Pour Homme.

Then there's a lighter, basic summer citrus, with enough melon to keep it interesting and enough bergamot to keep it from being orange juice: Ferre Bergamotto Marino I wouldn't exactly call this one similar to the Issey Miyake but would call them too "clustered" if they were my only 2 bottles.

I'm a big fan of vetiver-notes in the summer, as it never sits too close to any other type of fragrance, especially the usual department store suspects (nothing wrong with those!) that you smell often. The best Vetiver circa $50 at any volume, and you get a tub full of it: Comme des Garcons Vettiveru. Green and clean in all the best of ways! But you definitely want to try a Vetiver (any vetiver) before you buy any full bottle. It's a great scent to mix into a rotation but probably not your one-bottle-quiver.

Tech note: the second two suggestions are EdC's but wear like EdPs, which, if you're not reading /r/fragrance, just means they're not as light as Eau de Colognes generally are relative to their more concentrated Eau de Parfums siblings. Terms are just a hierarchy of how much fragrance they have relative to unscented filler used as a carrier. But like everything in fragrance there's not a lot of hard rules.

And for my last trick, try this guy: Generic ISO E Super Don't bother going down the rabbit hole researching this "Molecule 01" as it's branded. I'm sure I'll get yelled at for even suggesting it. But it's nothing fancy; it's a synthetic that's used in a lot of fragrances, in fact. The dicey part is that a company decided to try as a one-note-wonder. Nothing wrong with one-notes per se, except it's a bit dirty charging $150+, implying that this synthetic is derived from moonlight and unicorn dust, when it's a generic $2 chem experiment. So there's a lot of animosity surrounding it. Nevertheless, it has its uses. For one, it's light. Nothing sticky about this on any summer day. Next, it lasts all day. Not like you doused yourself in Grandpa's cologne at all though; it's staying power, not volume. It has this weird way of disappearing for minutes, hours, etc, and then popping up again. Never smells stronger or weaker, but just waxes and wanes during the day. Which frankly I find kind of nice. Finally, and perhaps most interestingly, it layers really well. Throw it on your skin before you get dressed so it's not right up in your face. Let it sit while you do your morning routine. And then use another "real" fragrance (play around!) on your skin after you're dressed but before you leave the house. The synthetic will last forever and subtly change the way your "real" fragrance smells. Not like you hosed yourself with two different bottles. This synthetic in particular is "cedary" so it can darken up some citrus and natural, light, scents. There are other synthetics, including another sold by that ebay link, but I haven't found it to play as nicely. But it does open the door to more experimentation and modification by you as the wearer of any fragrance. Probably not your best solo pick though.

sorry to all the haters, I'm just going with bang-for-your-buck utility here, and there's a solid amount of utility in ISO E super. Note that some people legitimately can't smell it at all, due to the synthetic's physical size, IIRC. Smell is pretty subjective but this guy can literally be a non-entity to some, you included. Hence, another reason to buy the generic (literally ISO E Super mixed with some perfumer's alcohol) and just play with it.

Sorry for the long post. But basically, just have fun with it. Try decants/samples instead of buying a full bottle so you can do a pub-crawl of scents before you commit, if you're on the fence after reading too many conflicting reviews (which often happens.) Good luck!
