I’ve seen this font in a lot of 1990’s material. These specific pictures were taken from the Instagram account @yvestumor & I think the images were produced recently but made to look 1990’s-ish. 
It is similar to Century Old Style but the characters are slimmer in my opinion, & the serifs are a little different.

Looking for the exact font, paid licensing is fine.

As far as I can tell, it is the same condensed* Didot used on the website,** but with an added thick outer stroke.

* Most probably artificially condensed, looking at the spine of the |S|.
