Um, not sure "Men will love to grab your ass in these!" is a particularly great selling point...

This isnt an ad targeted at the consumer, its an ad targeted at purchasers. Read the text

I did read it. Point still stands.

The point doesnt stand at all because the person the ad is for is not someone who will be wearing the tights. In 1959 I doubt that many (if any) women were corporate purchasers, as women’s products were sold by men at the time. This is an ad targeted at the men selling products to women, which it was probably very effective at

what else to say though?

Then you are a fool. Being more attractive has always been one of the best selling points.
