Enjolras 11, 14, 15? :D
I think at first he wears a lot of neutral kind of colors: navy, black, gray, but he always dresses nicely (though the odds of his cravat coming untied are high) and his clothes are probably well tailored. But because I am one of those people who can’t let go of the musical red symbolism, I DO tend to imagine him wearing little bits of red when his friends start giving him things. Courfeyrac starts off by giving him a red cravat, Enjolras decides he likes it, and soon it becomes one of his favorite things. Then Courfeyrac (or Bahorel) gives him a red coat, and so Enjolras falls in love with that, too. The red thing for me is suggested to him by his friends who think it suits him, until he stars liking it himself. But whatever red he wears would be the only flashy thing, the rest would be neutral.
I think he’d be pretty light on his feet! He’s not Courfeyrac, who is the Most Suave dancer (along with Bahorel and Joly, probably) but he can waltz pretty well.
I think Enjolras probably has a nice voice? Not like, opera singer quality, but I take that “voice that sounded like a hymn” idea to another level. I think he’d have a really nice, soothing tenor and sometimes like to imagine him kind of softly singing to an ill friend? Like, if they were really ill, and no one else was around.
