How '70s do these photos look to you?

[Silver Gaia]

30. All but the first one are most likely from the 70s.

In the first photo, the beehive hairdos and excessively teased hair definitely indicate early to mid 60s, and so do the skirt lengths. By the 70s, long, straight hair was in style, as were miniskirts.Especially with that many girls together in a photo, it's highly unlikely to have been taken in the 70s.

I am also unsure about the catalog page. I don't recall wedge heels being very popular in the 60s or the 70s. And the skirt length and pant leg width looks off, too. That one could even be from the very early 80s, but maybe could be from the late 70s.
