Have you ever wondered what Danica Patrick or Simona de Silvestro wear under their racing firesuits? I’m sure lots of people have or would like to know. This fun ad for Eiderlon panties might give us a hint although the ad ran in 1973. I expect Danica and Simona would wear a thong as we are now in 2016 and panty styles have changed a little. Certainly don’t want panty lines while posing in your fireproof nomex suit.
This ad ran a lot in Seventeen magazine. I wonder what GoodYear and STP have to do with it?
