Guess that scent. A game:

+1

One of my favorite bottles ever!

Sorry for draggin' my feet you guys, I've been super busy!

HINT #1: Almost all of this designer's bottles are more decorative than other lines.

HINT #2: This designer's second most well-known perfume's bottle is shaped very similarly to a very famous Guerlain perfume.

Oh, and sorry, Greysolon, Cincy, and Beachgirl2, those are good guesses, but not what I'm looking for.

Could it be Guerlain Les Parisiennes Mayotte Eau De Parfum

Naw, that can't be right, you said it was very popular.

Yes, VERY popular. And it's not a Guerlain. "Almost as popular as Chanel No. 5" is a big hint.

Enhanced Hint:

HINT #2: This designer's second most well-known perfume's bottle is shaped very similarly to a very famous Guerlain perfume recently mentioned here.

I guess that would be Shalimar.

I was going to take a Chance and say Coco Mademoiselle until I read your last hint.

Cincy,
Shalimar is the similarly shaped bottle.

I will wait just a bit to see if anyone else ventures a guess before giving another hint.

Yes, wait for sleuth you know who you are. and others, to be fair.

HINT #3: This perfume's bottle was designed as a post-war tribute.

I have no idea at all.

How about a hint about a note or two... I have no idea even where to begin!!!

L'Air du Temps by Nina Ricci? The fragrance was launched post WWII and has a dove on the top as a symbol of peace.

EXACTLY!!! That's it!

Wow, really? Man, that was tough! I did so much head scratching over that one I've got a rash!

Good job!

Sorry! I hope it was at least a little fun? It's been listed as a top seller right behind Chanel 5, so I figured that was a decent clue, right? And if I'd given the last clue first it wouldn't have been such a brain teaser.

Okay, Greysolon, it's your turn!

Since I bet we were all overloading Google searching for that last answer I think this might be a little easier...

Don’t worry, his fragrance line will not put you on the verge of a nervous breakdown.

What is the name of the fragrance line?

Greysolon,
Was there a clue in there? If so, I think it went over my head.

It's a celebrity line.

Is it the Britney Spears line? She has a song called "You Drive Me Crazy", so I'm thinking perhaps that is what you were referring to when you told us not to worry, it would not put us on the verge nervous breakdown.

Sorry, Beachgirl, it's not Britney Spears. Remember that I said "his line..." And even though you're on the right track, I've never heard him sing.

Justin Bieber

Sorry, Cincy, the man who is the namsake of this line is not a singer.

And as I told Beachgirl2, she's thinking of the clue in the right way.
