Grass, cut.
A number of years ago, Gap sold some unisex fragrances, one of which was Grass. It smelled not unlike a freshly-cut lawn, which ranks very highly on my scent-o-meter. (Off the top of my head, 
I can't think of a better scent, but I'm open to suggestion.) Anyway, it wasn't long before Gap discontinued Grass because, well, it wasn't a top seller. What, you don't want to smell like yard work?
I've hoped to come across something similar, but I haven't been terribly lucky. There are a few bottles of vintage Gap Grass lurking on ebay, but I wanted to find something more permanent. The good news is that I've just found a potential replacement. It is also good news for you, scent lover, because that same manufacturer, Demeter, makes all kinds of wonderful odours, including:
Laundromat, Jelly Belly Hot Fudge Sundae, Fresh Ginger, Cannabis Flower, Mojito, White Russian, Dirt, Waffle Cone, Wet Garden, Snow, New Zealand, Funeral Home, Fireplace, Dust, Dregs, Humidor, Lobster, Crayon, and Play-Doh.
This is the mother lode of smells.
I will not argue that grass is a good scent, but my favourite scent has always been almonds and Demeter makes an almond scent too. I might have to get me some!
Cut Grass ... ewww. For some reason that smell always makes me a bit nauseated. If you want the grass smell you could always go roll around in the grass ... wear a white t-shirt and then you could say your making the bold statement about underpaid landscape technicians or it's a subtle protest against cosmetic lawn care.
I'd much prefer things like cinnamon, vanilla (I know those exist), apple pie, chai latte, lemon meringue pie ... hmmm, I'm seeing a pattern here.
Almond is good. How about toasted almond and honey ... opps, there I go again.
almonds = cyanide.
Lucky for you Jimmy, those scents are widely available everywhere in just about any form you could want. You generic scent-lover, you.
Neat find; though why wear Laudromat smell when you can just wear clean clothing?
My only concern is that looking over the list, some these scents would make either (or both) Aly and I sick due to allergies. Though that begs the question. Are these scents synthetic?
The answer, dear Ian, is that the scents are as natural as the manufacturer can make them.
"Regarding essential oils, the percentage varies by scent between natural and artificial ingredients, with a bias towards using the highest degree of natural ingredients possible."
"With over 200 different scent formulations, we very rarely hear of negative reactions. The common factor among all our different scents is in what they lack – the colorants, emulsifiers, and binders. Consequently, we draw the conclusion that those are the culprits."
Glad to help.
Dirt? Dust? Who are these people?
