What is more important for you - the bottle design or the perfume itself?
The design or the smell? What is first ? :)
Smell? While I do enjoy a great bottle design when it's a bonus that comes together with my smell purchase, what it looks like begins to matter at all only if the smell itself is good. Otherwise I couldn't care less.
Definitely smell but design is important too. It would take an amazing scent to make me buy a bottle that I hate
I am a creator myself, and I could say that if I saw an incredible bottle but didn't like the smell I would buy it anyway 😂. But I never found a bottle I wanted. So, I did it myself ) But, I can say that the smell is really important, of course.

I think if I was asked this when I owned my art website it would have been the bottle swaying me if there was something I saw that I thought would make for a good art project, but now i definitely pick smell first as I don’t do as much art these days and I am always looking for the next scent that excites me as when I first started collecting fragrances. I am essentially collecting scents over bottles.
I do however think that when spending over a certain amount of money that brands should put some effort in to making their bottles look nice. Yes I do love a good looking bottle 😁
I also think that the functionality of a bottle is important, for example the atomisers, magnetic cap and pressurised bottles, but I think you are meaning aesthetics over function.
The point is, that it has to be functional and convenient! Of course! I love vintage style and I love functionality! I vote for refillable bottles to not throwing away the empty ones.
And! One more important question: what would you buy: A scent which is typical, the bottle has some design elements of plastic - for $400, but the brand is famous, or hand made glass design bottle with an interesting scent for $250, but the brand is small and unknown?
My favorite perfumes happen to have simple bottles. That is fine by me.
I do think, however, if I loved a perfume with an exceptionally ugly bottle design, that would piss me off!
Examples of perfume I am grateful to have little to no interest in:
Have you ever tried Avon perfumes in those strange bottles?
For me, smell is more important than bottle design. Ideal for me would be to have a great fragrance in a sleek, square/rectangular bottle.
I understand that some bottles can be a work of art -like some of Guerlain bottles for example- but I would not buy a perfumes just because of the beautiful bottle design if I don´t like the smell. On the contrary, I admit that sometimes, bottles that are way too ornate or glitzy even put me off.

I have bought many fragrances that I love but dislike the bottle. I would never buy a beautiful bottle if I dislike the fragrance. So yes, the smell is much more important for me. Of course if the bottle is absolutely gorgeous it makes me want to test the fragrance but I won't buy it if I don't like how it smells. If it's a cheapie and I love the bottle, I might blind buy it, but I would never blind buy an expensive fragrance based on the bottle design only. So a beautiful bottle is definitely a good bonus but the smell is what matters most.
The fragrance. Design can cause me to pass a fragrance by without testing it. It won't cause me to make the purchase.
I will never buy a pretty bottle if I dislike the scent, but I will most likely buy an ugly bottle if I like the scent, apart from some exceptions.
That's nice if the bottle is pretty tho but well... I own several fragrances from Maison Tahité and they look like pharmaceutical products. 😅
