"Perfume is subjective", I hear all the time. What's heavy to one is light to another, what is pleasantly sweet to certain individuals can be 
overly sweet. Probably because we haven't really agreed on which terms to apply so that we have a codified language to describe scents. True, we use "fragrance families" taxonomy to distinguish them (floral, woody, 
chypre, 
aldehydic, 
leather etc.) and sometimes we borrow from taste (sweet, bitter, savoury/salty, sour) but what happens with more esoteric terms, like "powdery" scents or "dry" ones?

Google search "powdery dry perfume" and you will see in the top five results the mention of Guerlain's 
Chamade. Now, 
Chamade isn't particularly "dry" nor is it particularly "powdery" except in the end. I mean, sure, one could detect these nuances to some degree, but my mind would gush forth hundreds of other suggestions for fragrances before mentioning 
Chamade. Unless we're thinking of the slang term "dry powder" for cash reserves for an unforeseen difficulty, in which case, yes, 
Chamade is a great asset in the war against industry mediocrity. But I digress.
So let's break down the terms, starting with "dry" since it's the more inclusive one.
"Dry" is a term that can denote two things in English: the opposite of sweet (as in wines) and the opposite of humid (Just like "light" can mean the opposite of both heavy and dark). In the latter sense, it's easier to grasp the context: Dry fragrances don't have dewy, watery, acqueous elements that recall crisp vegetation, any expanse of water or dew drops on petals. They can be mineral-like and they keep you dry as a result. Think of woody scents full of cedar, sandalwood, oak, rosewood, birch... Like the trunks of trees and their barks, they have a solid "appearence" to the nose. Think of smoke and some kinds of incense.
The opposite of non-sweet when refering to "dry" fragrances is a little more elaborate to explain. Think of a fine dry wine which has a minimal residual of sugars. Taste a fine white Reisling and compare with a full-bodied Sherry. And later on, within those categories, try to detect the degrees of dryness or sweetness between a 
Fino and an 
Oloroso Seco. Tannic notes give a taste of dryness which bites the tongue (in a non-spicy way).

Same goes for fragrances: In his couture shop at 7, rue Saint-Florentin, couturier Jean Patou had the brilliant idea of creating a cocktail bar where men could drink and small-talk while their women shopped for their dresses. 
In 1930, Patou decided that this could be converted into a veritable perfume bar and Henri Alméas, his perfumer, was instructed to create "cocktail" fragrances: The results were the 
original Cocktail, Cocktail Dry, Cocktail Sweet, and 
Cocktail Bitter Sweet. Clear enough?
It's not accidental that most masculine fragrances aim at "dry"; it denotes a certain butch element! Dry notes in fragrances are usually provided by woods or some grasses (for instance 
vetiver), by rhizomes (
orris/iris), by phenols (tar-like essences such as birch tar, guiacwood, leathery compounds), by mosses (oakmoss, treemoss). There is no restriction as to which family they might belong to, though: Try the oriental 
Tiempe Passate by Antonia's Flower, the chypre 
Aromatics Elixir by Clinique, the woody floral 
Ivoire by Balmain, Chanel's green floral 
No.19, the aldehydic 
Pure White Linen by Lauder, the mineral cologne 
Eau de Gentiane Blanche: They're all non sweet, non humid, they will keep you dry on a warm summer's day.
And powdery, you ask? What does it signify when talking about fine fragrance? "Powdery" can be a subcategory of "dry", as powder by its very nature abhors moisture. Yet powdery can take sweeter nuances or drier ones, according to manipulation by a talented perfumer. It also hints at a feminine rather than a traditionally masculine smell, evoking as it does a million "cute" acoutrements: feather boas, white kitten fur, cosmetic enhancements and 18th century 
peruques, pastry making involving flour, and fluffy angora sweaters in pastel colours. Usually the categorisation is between "face powder" or "talcum powder" (also described as "baby-powder"). Face powder notes are more refined in feel and overall less sweet with a vintage, "perfume-y" trail, while talcum powder is simpler, usually involving a comforting, vanillic backdrop that recalls the famous lemon--lavender-vanilla accord of 
Johnson's Baby Powder. The no doubt amusing dichotomy of powder evoking both grandmothers (through the association with the scents they carried on from their youth) and babies is probably fodder for a psychology thesis on how smell perception is the most perverse within the human brain function. For the scope of our column, let's give some examples to clarify our point.
Face-powder-smelling fragrances include Hermès
 24 Faubourg, 
Ombre Rose by Jean-Charles Brosseau, 
No.19 by Chanel, Patou's 
discontinued Normandie, Creed 
Fleurs de Bulgarie, 
Jolie Madame by Balmain, 
Coriandre by Jean Couturier and 
Ma Griffe by Carven. Talcum or baby-powdery fragrances have an artistically acclaimed representative in 
Petits et Mamans by Bulgari, a cuddly powdery scent which truly charms. 
Cashmere Mist by Donna Karan and 
Flower by Kenzo are the rather grown-up version, aromatized with a little jasmine for the former and a clearly detectable synth violet for the latter. Try 
Teint de Neige by Lorenzo Villoressi: choke-full of powder! Surely a firm favourite of power loving folks!
US brand Philosophy was fully cognisant, when they composed 
Baby Grace, that Americans have fond memories of having their baby bottoms talcumed with Johnson's.
 And there's of course 
Baby Powder by Demeter for nostalgisers on a budget; or those who want it clearly spelled on the label...
We had talked about ambery fragrances which often evoke a powdery effect the other day, some of the ingredients involved into giving such an ambience being amber mixtures, opoponax gum (such as in 
the case of Shalimar), heliotropin, vanilla and 
several musks (try 
Habanita by Molinard, 
Must de Cartier in pure parfum, Kenzo 
Amour or 
Obsession by Calvin Klein to see this. And see how 
white musks can be powdery soft in 
Clair de Musc by Lutens).

But powderiness can be also rendered through 
orris/iris (
Iris Poudre even says so in the name), certain aldehydes (read more on which 
on this article), 
Iso-E Super when combined with 
certain musks and most importantly 
mosses (like in 
Aromatics Elixir, Ma Griffe, Chanel
 No.19, Knowing by Lauder, 
Coriandre, and Piguet's
 Bandit).
Moss contributing to the effect is an interesting case of chance discovery. I was puzzling myself for years trying to figure out why moss reminds me of my mother and of face powder. I am not alone, lots of women associate it specifically with vintage 
poudre de riz face-powders imagining them being slowly, decadently, glamorously fluffed on with ostrich-feather puffs by film noir heroines before they go out to wreck havoc on some poor men's lives. Powders from Cyprus I knew were based on the famous "recipe" of chypre perfumes. Until one day strolling the Max Factor counter I stopped to read the actual ingedients on a couple of compacts, one of them being 
Creme Puff which both my mother and grandmother used with a wide brush for setting their makeup. Yup, prominently displayed was 
Evernia prunastri, otherwise known as...
oakmoss!
