So, that said, I have three suggestions for naked's and they are longer form than both of the suggestions in the description thread.
All your nakeds should stand on their own. Codedly, they have too. If you look at one of your nakeds, and say, well this references something that's not visible when that naked is on it's own. Then you've done something wrong systematically.
Good example of this rule being broken, just kinda spitballed here.
naked back is Her back is a patchwork continuation of the features on her limbs, gnarled and ugly. With a hunch that forces her shoulders down.
All your nakeds and for that matter features like them,(voice and scent and whatever else there is) should be descriptive and not vague. And also be relevant no matter what and where you are.
Good bad example of this,
Their eyes pierce you with a gaze that seems to look at you with disdain and peer through you.
First off, what if you're in a room with no people. At that point you are breaking the fourth wall.
Second off, what if I'm hidden and looking at you.
Hawk-like, their eyes peer out, taking in the area with a slightly squinted look of disdain.
Don't convey other people, convey how you are interacting with the environment, if you must.
Account for situations, and update your nakeds regularly.
Got your eye shot out, well you're gonna have a new scar there probably, write it in.
Had sex, add in some references to claw marks on your back naked.
Been grappling outside, add some minor scuffs and scraps to your legs and arms.
Trust me this stuff adds a lot of shit to the game, and makes people enjoy roleplaying with you more. I've had scenes where at the end I've OOCly been like, "So what minor marks would you have left on my body?" Even in a fight where that person missed every hit, negotiating a little something that they might have done mid fight roleplaying wise, engages them. Even something as simple as having spit in your head naked after someone spits on you.
Finally, keep it simple, no one except MOOsexers want a 3 paragraph description of your groin, including glans size, status of circumcision and explicit description of length or puffiness. Less is more, in almost every case here.
