@GumboAwake OOF— WAIT let me think about it (sorry for the late reply, AND THE QUESTION IS NOT WEIRD ITS A REQUIRED DETAIL)
_____, smells like what you readers want her to smell like, that's why I don't really go in dept about that in the book.
But since it's my personal opinion, considering your lifestyles back at the sphere.
I believe that you would smell like the aftermath of the first rain fall after months of only sunlight(sappy and cringe I know but cringe culture is legit how I survived)
You do wear perfume but very rarely, because you sometimes hates how extravagant the scents are back up in the sphere, if you ever do wear colognes you would try something akin to baby colognes, something not to strong for your taste.
But that can change randomly throughout the days, something about you is that you hate feeling unsure and uncomfortable of everything else, so you developed a coping mechanism to help you through it.
And it's by wearing the perfume of the people you care and love for.
SO YEAH^^ That's my little opinion.
