One of the big themes for 1980's jeans adverts was the use of 50's style and 50's/60's music. Jeans are synonamous with American culture and the translated word for jeans in many other languages is actually something closer to 'cowboy pants'.
Jeans are a staple of many retro guys & gals, particularly if you favor the Atomic Age for your lifestyle, also for greasers, mods, hippy chic etc. There's a nice article on Mooky Chick by Abigail
Stephenson about the history of jeans.
The thing about jeans is they are supposed to be hardwearing and a little rebellious. They aren't just workpants they indicate something of the traveller, someone who isn't dressed for church but for adventure, for living. It can be tough to find your perfect jeans but it's not impossible! I LOVE 50's roll ups and little capri style jeans but I know what looks best on me is 70's style flares.
In any case adverts had wanted to be seen as modern. The concept of using a song like Percy Sledge's When a Man loves a Woman was an anathema to everything happening in the marketing world. But taking off from the 'Golden Age' of America, the post war boom years, was exactly what worked on young shoppers.
Apart from being a great song, it was wonderfully stylish and idealistic period focused on youth culture.
