Beyond what they have put down in black and white about the dress code, you just have to evaluate what the corporate culture is there. If they play it conservatively, and by that I mean, they don't like much change, then they might have an issue. If they tend to be more open to change and new ideas, then it might not be an issue.

I'm assuming that have a dress code because of the machinery in the area and they are covering themselves legally. If that's the only issue, then I don't see a problem since skirts are allowed. The way it's written the code only asks for people to dress professionally.
