Ignoring the age gap... I think they could look pretty cohesive together, with a mature, classy concept. And not mature like "inappropriate", just like really chicly styled like the girls wear highly "feminine" style and the guys wear highly "masculine" style.
I also think chill R&B inspired style would suit them. At least for the girls. I don't know much about the guys.
But disregarding my opinion, what do you think?
