1. Bain de Soleil. By today's standards this is a pretty tame commercial, but there was a good deal of skin displayed in a pretty seductive way.
2. Underalls. Again, nothing really risque, but that tilting butt at the end that went "tink tink" was kinda arousing.
3. Playtex Cross-Your-Heart Bra. I suppose any bra commercial would qualify, but this one stuck in my mind.
Edited to add: Dr. Zibbs reminded me of this one. I was trying to remember the name of it and when I saw his comment it popped into my head - Enjoli perfume.
