This could be an idea It's true that Robert has very beautiful eyes. But I don't know if he would like to be associated with the "image" of a cosmetics brand. Do you already think of his retraining ?
Robert originally did it to hide correct? More of a statement the way he wears it rather than a fashion show.
I don't know about hiding but he's been quoted saying he would wear make up in school because he liked it abs grew thought he looked better... Who knows how much truth are in his words.
I remember now, my first boyfriend also put on makeup from time to time. He pricked my makeup in my kit, especially the powder and the foundation. He also said he was better. And for us, it's exactly the same thing. I think it's true for Robert. And besides, it seems to me that his wife loves him when he's like that. So, there is no better motivation !
