I uploaded my simself to Cstyles the other day. I'm pretty proud of her. She's kind of a 'perfect' version of me...perfect skin...no rolls. lol She's curvy, but sims don't actually have 'rolls' so to speak...even if they're enormous... I had to use pretty much every slider out there on the market to get her to look right...I have a weird face. lol And you really have to, to get a realistic-ish looking sim. She's not 100% accurate, though...I have a tattoo on my let arm of my mother's signature, a small tattoo on my left breast that I did when I was 16...no, it didn't hurt, but I do regret it...and the bottom half of my hair is copper. You can't really do that with hair in TS3, unfortunately, so I just went with my natural dirty dishwater brown hair. lol
I really love this pic...it explains me to a T.
Also, here's a pic of my arm tat...I love it...
