The logo belongs to the company copyright but the name Yves belongs to the person so they had to drop Yves and they just use Saint Laurent now on boxes, dustbags, and marketing. A lot of companies that sell YSL have reverted to Saint Laurent instead. It has to do with litigation and his exit, just Google the brand history if you're interested. imo the Y will eventually leave the logo as people get used to Saint Laurent more and more.Why aren’t they allowed ? Logo YSL is Yves Saint Laurent
