For Yves Saint Laurent I worked on a feature that allows customers to engrave their product and add a sticker. First, I worked on the UX part, on paper and Sketch, because different offers could be possible on that personalization module (engraving free or not, free engraving when you buy X products etc.), design should work on every case.
Then, I worked on artistic direction.
We launched this feature in several country and it works very well!
