Guess this typeface based on my description.

[Edit: sorry, changed my mind on what category this post would apply to]

I saw this font once but don't remember too much of it.
Saw it on a video online of a presentation- the presentation might've had something to do with typography.

1 The font was very light sans, or a "serifless roman".
2 It was a true italic.
3 It had proportions that might've been inspired by, if I remember correctly, Garamond.
4 It might've had swashes.

Wish I could remember more, but it was beautiful!
