Diane Keaton's awkward androgyny – as seen in 1977's Annie Hall – has been a fashion template for decades, preserved in aspic as a key designer reference. But thanks to Twitter and Pinterest, the actor's present-day style influence continues to evolve.

Keaton's Twitter feed is part motivational manual ("Who is an independent women you've loved?? And why? Tweet me pictures of them, too!"), part style bible, while her Pinterest is a monochromatic feast of fashion, interiors and photography. Both should be followed by anyone with an interest in fashion, Hollywood glamour or aesthetics – here's a recap of what they have taught us about Keaton so far.

1. Keaton is obsessed with hair. And she has had her share of tonsorial nightmares

2. Keaton finds inspiration in menswear – and she buys it, too

3. She finds beauty in a variety of places...

4. ... and has a lot of time for fashion's rulebreakers

5. She is also healthily fixated on Barbra Streisand's nose

6. And finds there is no better home style statment than a chic - and cheeky - book cover
