Stella Tennant hasn't smiled since college.

OK, that's an exaggeration. She hasn't smiled for a photo shoot in 20-something years. (According to Modelinia, Tennant made it a rule to never smile for the camera.)

Although Tennant retired from modeling in 1998, she still clearly has what it takes, as proven in these chic black-and-white shots by photographer David Sims for the September issue of V magazine.

What's more, she's broken her number-one rule by cracking a smile in two of the frames!

Did we mention she's 39 years old?

The Scottish native and her photographer husband returned to her homeland 12 years ago, purchasing a country estate to raise their four kids and occasionally posing for ad campaigns (including Ferragamo, Burberry, Givenchy, Louis Vuitton, and Marc Jacobs).

While Tennant hasn't walked the runway in some time, her editorial work is perfectly on par, don't you think?
