Please don't use any of my fonts.

@Nick Shinn Awe come on, Nick. You don't think any of this aligns with your own personal typographic ideologies? Not even just a hint of Sex in the City? ;)

Kidding aside, I am actually looking for something a little more classic. I don't want people to actually think these people are Mad Men meets Sex in the City. To compare using fluffy entertainment and is probably selling them way short (they are quite brilliant people). Which might be why I'm having trouble zeroing in on an appropriate typeface.

Thanks for the early suggestions!

Great description. Makes me think of Jeanne Moderno, which strikes me as classic but different, and feminine in a strong/rigid way.
Also look at FF Pitu, maybe that's too sharp tho, but definitely classy and very sexy.
A softer, sort of classic solution could be Mrs Eaves, but you don't want to don't use that for anything longer than a wordmark (where you would manually kern it).

How about Feijoa Display? - http://www.vllg.com/KLIM/Feijoa#panel=poster

Eames Century Modern http://eames.houseind.com/fonts/

Yeah! Now that's what I'm taking about. Those are some great suggestions, thank you!

I'm especially loving Eames Century Modern. What a beautiful collection. It seems to be very fitting in terms of the historical influences and the aesthetic I'm going for. Thank you, all about seb!

Also a big fan of Feijoa and Jeanne Moderno. They might be good backups to experiment with if necessary.

Ah! Nice.
In the general direction of Eames (which I admire too), you might also like Sentinel (which might be a bit more masculine); maybe also check out Parry (which is a bit softer / more playful).

You lost me at "strong but feminine".
In my ideology, those terms are not mutually exclusive.

"In my ideology, those terms are not mutually exclusive"
Um, not in mine either. But I too have found that stating them like this often helps in communication because to most people, when you request a «feminine» font, they'll name pretty, decorative, swirly, floaty-elegant designs; not «strong» ones. So while I personally wouldn't necessarily put the «but» there either, I understand that it doesn't need to come from a closed mindset but maybe just from trying to prevent a too-common, unintended reply. Now do we seriously need to argue if the original poster would correctly have to ask for a «strong and feminine» font instead?

@Nick Shinn Okay, obviously I meant strong and feminine. Nina, thank you for helping to clear that up. That is exactly what I was going for. No mutual exclusivity intended. At all.

Nina, thank you for helping to clear that up.

I don't think so, but I'm not going to press the point.
