Rita!  Only good looking bitches named Rita!  Big fat black ones 
 
Really it depends on what the popular girl names of the decade were.  Don't try Wilma or Connie, they're rather older (or atleast puts the idea into another's mind.)  Follow?  Just think what most 18-21 year olds names are, or whatever target age you want them to think....  I don't think if you name a girl Celeste she always looks good...
