Scars... tats... piercings... no problem (within reason)

Scars - no worries. life is not about being put on a shelf and remain untouched a porcelain doll.

Tats - I've got them, would be a bit hypocritical to say I wouldn't date a woman with them. That being said, all things in moderation. I dated a girl who was covered in dragon tattoos... not exactly a "bring home to meet the parents" kind of girl. The most recent x had multiple including a killer back piece. But she could fit in to a conservative world with no issues. Her tats were for her and no one else.

Piercings - some things need boundaries. Pierce what ever the hell you want, but damn... keep them out of your face. I'm not talking about nose or eyebrows (if people even still do this one), but lips, cheeks, whatever else... no thanks.
