Are sneakers appropriate wear for a trip to the White House? Jimmy Butler thinks so. Frank Ocean does too—the crooner donned a plain pair of Vans Slip Ons for his appearance there on Tuesday for President Obama's last State Dinner.

His wardrobe choice caused a bit of controversy, with one reporter questioning the checkered sneakers.

"You can't think, you just have to do things," he said when questioned about the rationale behind his decision to wear Vans.

Accompanying Frank Ocean to the dinner (and not wearing Vans) was his mother, Katonya Breaux.
