Ok, this sounds weird, I know. But I remember seeing a topic similar to this on the old board. I've searched high and low for it, including all 21 pages of the old defendant's lobby, but cannot find it for the life of me. Anyway, that topic was the one that introduced me to Black Phoenix Alchemy Lab http://www.blackphoenixalchemylab.com/welcome.html, a perfume oil retailer online. Now that I actually buy oils from there, I wonder which of the oils PW characters would actually resmeble. The only one I remember was
was whip, big surprise.
It's blatently obvious what I smell like!
I smell like....sake....
Smells refreshing like a spring breeze.
The scent of 
- Smells like a fresh baked cinnamon rolls (damn that's a good smell).
Hopefully not like the homeless people in the library (which is a fascinating combination of urine, body odor, and sewage that lingers in a spot five minutes after they vacate... I wish I was kidding).
Horses and whiskey. Mostly whiskey. I mean what else could be in that flask.
Elmer's Glue. We used to use it for massive hair spikes back in high school. I imagine it'd do the trick for Daian's hair as well.
Chlorine. Obviously.
Greasy tortilla chips. He reminds me of a guy I had a class with that smelled just like that. 
Cotton Candy. I'm sure they still make candy scented perfumes, right? blech..
Smells like cat.
Just to state the obvious, he smells like watered down tea.
Bananas...
Pheremone d'amour.
smells like money (is that even possible?)
smells like (wriggling) plywood.
well, one of his aromatherapy oils, that's for sure...
cheap cologne
More or less the smell of hamburgers... I swear that girl needs to diet!
I actually imagine him smelling quite nice, probably wearing a nice kind of cologne.
Probably the same as Phoenix, but a more expensive brand.
Um.... stinky... from the way he scratches, its like he hasn't bathed in a while.
may be just the fresh scent of child skin :) I can imagine her clothes to keep scent traces of wild flowers, grass and a really cheesy kids' shampoo.
should remind you of an old house, but way more intended. More.. like bitter almond.
might use a very deep rose perfume. Not the type that lingers in the spot for minutes, though, just deep.
Lovely hair smell, bamboo, fresh cucumber and green tea. No perfume.
I imagine he would use a pretty good sharp cologne, just a bit too much of it. Apple in the top note, Cedarwood and Olivewood in the base. Cloves in the heart note.
A little like a zoo's tiger. Cleaned and not 'authentic', but still like a wet, wild cat.
Very rich melon bubblegum. 
Citrus, basil, perhaps juicy pear and honeysuckle. Classier and young, but not sweet.
Tabac. I'm 100% sure of this. It's a (very nice!) cologne for men with bergamot, lavender, neroli, oakmoss and tobacco back from the 60s. It's popular with scene women, too.
dairy milk chocolate 
light perfume, something like Dolly Girl
smoke and opium 
puppy shampoo
bird poo
tea roses
coffee grounds
no smell or mabey like a hospital from trying to get clean all the time 
bacon
like an angry day at the beach! (or the air after a hurricane *_* )
nice perfume and hospital 
old spice
Juicy Couture parfum (very sweet and feminine and cost $300 an ounce), new car smell
Pure Poison (the perfume I mean)
- Freshly unpacked computer hardware
- Various chemicals
- Diamonds
Chlorine, leather, and maybe some light cologne. 
Thunderstorms - they DO have a smell! I swear to god
Clean clothes and a kind of floral perfume. Like daisies or something.
essence of breast
Allllll sorts of tasty foods. :D
Cameras? plastic probably XD
Luminol and some cute floral/fruity perfume. 
Pressed clothes and old people and failure. And hair grow stuff
A sort of overwhelming sweet cologne/perfume. Like, block out anything else you smell overwhelming.
Animals and a cute fruity perfume - like cherries or strawberries
Feathers
Pencil shavings and paint
cheap perfume and faint plasticy-smell that never goses away
ashes, incense
iron 
bananas and custard pies
