The 'Marilyn Monroe' singer swapped his famous Vivienne Westwood felt Buffalo hat for the new headgear in an exclusive interview and photoshoot for Elle UK.
Asked how his model wife Helen has helped him shape his creativity, the 'Happy' star said: "We just motivated each other as friends. She pushes me. I push her."
Meanwhile, talking about his Buffalo hat, Williams added: "I remembered (Malcolm McLaren's) Buffalo Gals video, where he wears the hat. I actually wore it five years before I was photographed in it, it's just that no-one was paying attention at the time."
On good manners and understanding the value of things, he said: "I wasn't always that way.
"I took a lot of years to understand the value of things and the value of the people you work with," he continued. "The value of your fans who ultimately hold you high and lift you up. We're just hang gliders, dude, and they are carrying us around."
Williams was recently interviewed by Krishnan Guru-Murthy for Channel 4 News, in which he said that he doesn't see himself as a feminist, admitting: "I've been asked, 'Am I a feminist?' I don't think it's possible for me to be that."
When Guru-Murthy responded that it's possible for men to be feminists, Pharrell said: "It makes sense up until a certain point," adding that he "[does] support feminists" and expressing that there are inequalities that need to be addressed.
