Got this Cardigan, want some color tips?

[2betailoredl8r]

I got a nice white fleece cardigan from Ralph Lauren, and I tend to have a pretty preppy style generally (especially in the summer) and while i like it a lot, I'd like some suggestions for what to wear with it? all suggestions are appreciated (telling me "just return it" or something of that nature, is not)
