no...The 80's and 90s are well past.
Many of Brazilian chicas posted got tan lines, Brasilians with tans=sexy.
If you have a booty and a brown complexion, tan lines help outlined the goodies.
A woman without booty and lacking a brown complexion= 80s looking.
So, to answer your question Newmom, tan lines are conditional. They look good on a swarthy complextioned person with a good body. On a Nordic looking woman, not that well.
