don’t you know???
That is the uniform of Silicon valley. Apple founder Steve Jobs had the trademark black turtleneck and jeans.
Here’s the difference:
1) Jobs was 30 years ago..not cool to imitate either, you couldn’t figure out your own signature “trademark look”, Suckerberg.?.
2) Jobs Tshirts and jeans always fit well and he did wear suits at times.
3) Zuckerberg’s clothes are cheap and very ill fitting.
Summary: Zuckerberg is a slob. A lucky slob, but a slob.
Californian style. They hate suits.
