i mean.... that's basically semantics considering he cosigned, pushed and rocked it. a "creative director" isn't necessarily designing all pieces either, more so in charge of the designers.
How is basically semantics if he even by your own words he was just essentially marketing and the face?
Co-signing, pushing and rocking something doesn't mean you designed it, my nikka.
Wayne and soulja boy did the exact same thing. Do you consider them as designers/creators/etc of bape or a famous consumer bringing eyes to a product they enjoy?
None of the aforementioned are determining colorways, textures and designs of every shoe.
A creative director literally leads the direction of creation which means all work underneath your line is you and falls on you since you have final word of approval and dictate designs and everything else.
Pharrell literally just liked the shoes and decided to rock them in America and make them popular.
