Guess that scent. A game:

Yes indeed Cryptic!

Woohoo!

I'll try to come up with something quickly.

One house, six perfumes:

She wore a blue dress and a white pinafore

He had a cheesy grin

It was slain by a beamish boy

He wondered why a raven is like a writing desk

Jefferson Airplane song

Game played with hedgehogs and flamingoes

Oh, that most prolific and clue-friendly house, Black Phoenix Alchemy Lab, with the following:
Blue dress: "Mad Tea Party - Alice"
Cheesy: "Mad Tea Party - Cheshire Cat"
Beamish boy: "Mad Tea Party - Jabberwocky"
Raven writing: "Mad Tea Party - Mad Hatter"
Jefferson Airplane: "Mad Tea Party - White Rabbit"
Flamingo game: "Mad Tea Party - Croquet"

Yes! CS Lewis led to Lewis Carroll in this case.

This one should not be too intellectually taxing:
Some really ugly bottles
From this law enforcement brand,
Perhaps they're making perfume
After being in a band?

The two I deem most heinous
Have 'gold' details - far from plain,
And the sprayer's in the crown
So you can siphon out the brain!

I guess you are talking about these epitomes of class...

To Be - The Queen

To Be - The King

I wonder why Police has not arrested their creator already...

You have chosen correctly GothicHeart.
I'm a collector of skulls but even these crossed the line from cool to kitsch for me (I think that gold dental grill sealed the deal).

A collector of skulls... That's why I love Parfumo! No boring people here! I'm sure there's someone collecting crossbones around...

He may be one of the best that France has ever made.
A ref. of masculiniity, although with rose galore.
A blue eyed serpent matched his eyes, back in the '80s fade.
To find its namesake, one should go to East Pacific's shore.

I'm at a loss, GH. I've thought about cobras, vipers and other assorted reptiles. I've even tried to spot a perfume that matched the geographic clue by going through every perfume released from 1980 through 1989. Nothing pinged.

Time to narrow things a little then...

One of its dad's most famous works was done in what is known
as a renowned italian hat, but also a perfume house.
He's not a perfumer per se, but many scents he's grown.
One of them is our wanted one's lil sister or its spouse.

Its namesake's lying in a land whose fights with Spanish Crown
have left a bump upon its head which... Lo! It's Ecuador!
It sounds a lot like febrile pests, which they can bog you down,
but while the suckers are still here, alas, our scent's no more!

Oh. I think the light just dawned. I need to look at a map of Ecuador, though.

Well, the map was not helpful, but otherwise my guess fits some of the clues, so what the hay.

Nose = Uncle Serge?

House = Shiseido?

"Italian Straw Hat" premiered at Theatre du Palais-Royal, and Palais Royal is the name of the Serge Lutens salon in Paris?

Perfume = "Nombre Noir" <--- contains rose, launched in 1982 and is discontinued

Spouse (by a civil union) = "Serge noire"

Little sister = "Une voix noire"

Ecuador... I dunno. Numero negro?

Unfortunately not even close Cryptic, even though it was quite an effort...

Although not in NATO's ranks, this country's major city
in its phonetic alphabet it uses to appear.
Its father's nearly eighty now, but still he's looking pretty.
It came to life, in olive glass, in Maggie's third term year.

Okay then! I think I'll leave this one in Triffid's capable hands.

When someone "fails" in guessing, there's always a chance that the problem may lie in the clue. Now, this is the furthermost I can go...

If you remove the perfume's self and join its remains
with one of those they're trying to ban, minus its second "s",
then there you go, you'll have the pest which drinks what's in your veins.
"I give up bone" could also be another way to guess.

Margaret Thatcher ('87) and 'olive glass' have led me to "Iquitos" by Alain Delon (Iquitos being a city in Peru).
You know, my original guess, before the extra clues, was going to be "Snake Oil (1989)" by Santa Fe Botanical Fragrances! I knew it was totally wrong but we did have the year, the geography, the snake reference and the logic that anything deemed 'one of the best" would have to be the sly words of a snake oil salesman.

Which work miracles I might add! Spot-on Triffid! However, I'd like to get some feedback on whether my clues make any sense, or they are absolutely poppycock. So, how many pieces of "evidence" do you ladies think can be extracted from the verses, now that the perfume is known? I counted about fifteen, give or take a couple.

Gothicheart, there is no problem with your clues. They are labyrinthine and challenging in the manner of all good mysteries.
I think that sometimes I don't approach the problem the right way. I may be rushed or I select a phrase or two, forget to keep an open mind and then pursue a dead end.
For example: with the last riddle, I started by looking at years of release in the late 80s. I passed over Iquitos because: a)I had no idea it was a place and fulfilled one of the clues, and b) I erroneously assumed that "France's best" referred to the perfumer (nose) or perfume and the answer was likely to be a classic, famous masculine. And I won't even mention the snake....
Had I been a bit more attentive, those subsequent clues would not have been needed. In fact, I didn't use them once I knew exactly which year to investigate (thank God there were so many fewer releases pre 2000).
So, in summary, you are doing a fine (superior in fact) job of crafting the clues, it's all good, and it's just that there are only a couple of us still playing after a gazillion posts so the competition between answers and feedback is rather low. We are hoping some of the old timers (and new timers) will join in from time to time as we don't want to give the impression that we are game hogs.
I've been chided in the past for making clues too easy, so go figure!
And on that note, I shall have to compose a riddle....(please talk amongst yourselves for a bit...)

Ta Triffid!

These two connections were just brilliant!

So, 'sup Cryptic?...

Nice job, Triffid.

GothicHeart, in response to your question, this line really threw me:

He may be one of the best that France has ever made.

I think maybe you were referring to Alain Delon and his ability as an actor? I was hot on the trail of a legendary perfume, or so I thought. The clues were great; your puzzles always are, and it was solved in the end, which is what matters.

OK, here we go. A story about my historical role as the family's 'companion animal undertaker'.

A tragedy has just occurred,
The family pet has died,
As usual, I dug the hole
While household members cried;

Some kibble for the afterlife,
A favourite toy or two,
In they went with mumbled words
"Much loved by all who knew..."

I didn't wear a fragrance
As I toiled with heavy heart,
But here's the thing - I could have,
This one really fits the part!

Now, that was unexpected, to say the least! Although this may sound a little morbid, could it be Fang Fragrance - Fresh Grave by Damask Moon, as "Fang" matches the deceased pet if it was either a canine or a feline (which I suppose it was 'cause of the kibble), and "Fresh Grave" matches its last abode?

I can't quite believe you got it. Well done!
Those clues were indeed the key.
Not sure how this one would smell; perhaps animalic and earthy with top notes of fresh flowers?

My mother's yard was so full of deceased cats that planting was deemed hazardous (and those graves were getting shallower due to my lack of commitment and some unexpected bedrock...)

If someone had told me that there's a perfume called all that, I'd have actually thought (s)he was joking... But then I remember that there's something called 'Don't Get Me Wrong Baby, I Don't Swallow', which makes the whole thing plausible enough. What happened to the Poisons and Opiums of this world? But enough with philosophy, let's get back to business...

This time of magic came inside a comely obsidian phial,
put in a jade tasseled case resembling reptile skin.
Its house may sound a little grave, as it's of our last trial.
It no more looks that striking, since a time that long has been.
