I think it really depends on the campus. At my school, everyone wears Rainbows almost year round: rain, shine, hot, or cold. My chapter is even wearing them for a couple of recuritment rounds. So, it's definitely not uncommon to see them worn here with sundresses and skirts, people even go out to bars and clubs in them. That said, for dressier rounds of recruitment, I walked from house-to-house in flipflops and then changed into heels there. Then again, there's always the option of wearing a "dressy" flipflop.
