EYES
They're purple. #c84aff is my preferred color, but don't let my exact preference stop you from just picking a purple and running with it.
HAIRSTYLE
Look, I know it doesn't make much sense in 3D space. If you have to change it to make it work, change it. I'm pretty flexible on this, as long as it's still fluffy and around shoulder-length it's fine. Ponytails and the like are fine too
BODY AND SEXY BITS
If you flatten out Cami's belly I will attack you. I lack the skill right now to *really* depict it as I'd like to, but if you need reference on The Shape... well, he's my sona. I post nudes. You get the picture
Boobs non-optional. Relatively small compared to your average ridiculously sized Hentai Honkers
Cock is humanlike by default. You can either adhere to this or do something completely different, I don't care. Just don't get rid of it entirely without consulting me :P
Aside from the wool, Cami's generally free of bodily hair.
CLOTHING
i. CASUAL
Hoodie is loose - it HAS to be to fit over her horns. The hood is basically a useless decoration, that shit does NOT fit over her horns. Black tank top underneath.
Most of the skirt is hidden under the hoodie. Missing texture patterned panties beneath
ii. STAGE (suit)
The suit and pants are a bit tighter of a fit than the casual outfit.. I try to make the pants and lower halves of sleeves a bit wider for having so much fluff under them, but this isn't mandatory. Maybe the fluff is hammerspace cartoon rules, maybe it's realistically crammed under there. Who knows?
iii. OTHER SHIT
If you're planning to put Cami in a different outfit than either of their two "canon" ones, making it make some sense would be nice! You don't have to account for the tail (I usually just have it show through the outfit), but at least make sure she can fit the outfit over those big-ass horns... things that zip or button up, or are loose around the neck, work nicely.
The big Kingdom Hearts-ass boots are an essential part of any outfit. But if you really must, you can remove them... -sigh-... (in all seriousness, do whatever with the footwear. remove it for all I care, ya little freaks)
