graduation... what to wear?

DS's marine graduation is scheduled for Friday, November 13 in San Diego.

according to all the weather sites i've visited, the weather at that time of year is in the low 70s.

i need help figuring out what on earth i can wear for his graduation.

one person suggested not to wear a skir/dress because we'll be sitting on metal bleachers.

ok. give me your ideas.

thanks.

Re: graduation... what to wear?

I think I'd still wear a dress as long as the length is not too short.

I am thinking something like a nice wrap dress- so flattering and always appropriate.
