I work at a winery and I was wondering if a maxi skirt would be too dressy? I've worked there for awhile and I haven't worn too much dressier than a nice top and jeans.

I think that would be very nice. I love maxi skirts and wear them a lot to work. They are cute and professional. The only thing to make sure of is that it's not too long and dragging on the floor as a possible tripping hazard or else you might need to wear high heels with it. I have to wear heels with mine. :-)

I'd be more worried about the safety aspect of it. A loose flowy maxi skirt is likely to get caught up in the machinery and a fitted one is likely to hinder your ability to move.
