How can I get my girlfriend to wear a skirt?

She usually wears jeans, and is pretty fit, however I would really like it if she occasionally wore a skirt. I think they're a lot prettier on girls, and I just really like how it looks.

I think she's gorgeous, but is there anything I can do to convince her to wear one? I wanna take her to a nice place but she's trying to avoid it. She has often talked about how she wants to wear them, but just seems unsure.

Is it really uncomfortable to wear skirts? Am I being unreasonable?

She told me she bought a dress the other day, so excited about it!

Even though she didn't like them much at first, she's wearing skirts quite often now! I guess maybe it's just the first time that's the hardest hahaha...
