In the same GQ interview where Yasiin Bey talks about why he changed his name, his involvement with the brand Ale et Ange, and his ever-evolving style, he says Michael Jackson's death had an impact on his new look.
On his style:
"When my paternal grandfather passed a few years back, I started to wear a shirt and tie every day, like he did. Michael Jackson's death had a big impact on me, too. Right before the Ecstatic tour in 2009, I began wearing loafers and high-waisted pants. And that's where my look started."
