Rejeane is clearly the older of the two in this picture, and there's a starker contrast between the pair featured here than in the majority of Colette's images. That doesn't mean that there aren't still similarities, though.
First off, Rejeane and Marilene have very similar taste in earrings. Secondly, they may go to the same person to have their hair cut and styled! If Marilene looked upon this picture as a window into her future, we hope she liked what she saw.
