Does anyone know any K girls in bay area, LA ,or Las Vegas with tan lines I think they are sexy.

You might be lucky enough to catch a girl coming off a vacation, but if she is young, they will fade away, and if she is older, she will go back to the all-over tan preferred by mature Kgirls.  I took my Kgirlfriend to Hawaii last year for a little over a week, and she came back with tan lines, but she couldn't wait to get back to the tanning bed and even it out.  Its too bad, because I preferred the tan lines.  

 
We have an indie girl in LA who was a recent Ms. TER and her signature look is her tan lines.  Ashley Shye.  She's not a Kgirl, but nobody looks better in tan lines than her, IMO.
