I can't remember if people have asked these questions or not (sorry if someone has). I was wondering about rain gear--specifically trench coats and wellies.

I have to commute to school by bus, and then I am outdoors walking around on campus all day. Some days, it's quite rainy (you can't see a few feet ahead of you and rain is blowing sideways rainy). But these storms can come up suddenly, usually in the afternoon. If I know it's going to be rainy that day, can I just wear wellies all day? They are heavy, and it's not very practical to carry them with me in case it rains later on in the day.

My second question is about brightly colored trench coats. Do these stand alone the way specs and watches do? Most rain trenches are available in black or some shade of khaki, and I'd rather get one that is a flattering color on me. It might not necessarily "go" with my outfit though. Is this okay?

Thanks for any guidance you can give!
