OK, so I bought this dress. It looks semi-dowdy in this pic, but I think wearing it adds a lot. I felt great in it, so now it's mine.

here's a closeup of the print:

Trying to decide how to accessorize. I don't actually have any purple shoes, so I'm back to plain nude pumps. I also feel like I could dress it down with a denim jacket, but then the pumps wouldn't work. The site suggests black wedge espadrilles, but I still don't know about the denim.
Ideas? (This is conference-wear, btw, plus maybe the occasional work meeting here if the client is casual enough and I can dress it up.)
