... Agreed!
Kes' ears are really pretty cool-looking, actually. They're sufficiently 'complicated,' with all their fiddly-bits, that they're kind of interesting. Which is why Jennifer Lien's putting the kibosh on them was sort of jolting. Little changes can make such a big difference, especially in such a short period of time. But once you get used to her long wig, it does make her seem more 'mature.' Like it's just another step in her natural development.
That's just it. When I first saw the long wig it was a good way to separate the 'current' Kes from the rest of the instances we saw her (I think it was during Before and After, but I could be wrong). When the wig stayed, I easily imagined a deleted scene where Kes decided she wanted to look a little more mature and hair is a good way to make a change. I could also imagine giving her a wig/haircut that still showed her ears poking, but that was before I learned about the ears giving her allergies.

And when Lien was 30, or pushing 30 whilst still on Voyager, you're right ... it might've come across as though she had held on to something too long. Namely her youth - unless she'd modified her image. But for the 3 years that she was on, Jennifer/Kes rocked the elf look. Of the female cast members, Roxann Dawson was the hottest of them. I'm not into blondes that much, really ... but Jennifer was a truly beautiful woman, in her day. Some very good casting on that show ...
Actually I meant Kes growing up and changing her looks, not Jennifer but you bring a good point. Jennifer's looks do determine Kes' as well.
