Since your deleted post also removed my reply, I'll go ahead and re-write it;
If you understand Faris' character, you'll know what I'm getting at. The pirate ship isn't the only reason she dresses that way. Long after her secret is out, she continues to prefer masculine clothing. Galuf suggests she should dress more like a girl and she outright refuses. In Bartz' on words, "No point trying to change her... Faris is who she is!"
Thinking about it more, it's extra odd that while referencing a game that condones crossdressing with one of its main characters, we had to make sure men did not get the option to wear tights. I understand it slightly more when it happens to things like the crafted or artifact sets, which almost every player will use, so there's more pressure to be "inoffensive." But a level 1 glam piece behind hours of grind? Alas....
