Pharrell splashes out on cashmere 'Spongebob Squarepants' socks

Pharrell Williams has custom-made 'Spongebob Squarepants' socks.

The 'Happy' hitmaker is a big fan of the yellow cartoon character and spin-off merchandise, and found a pair of toe socks so comfortable, he decided to have some more made, but in a more luxurious material.
