I think you look so nice in the white jeans, Suz, and while I can't relate to the different weather patterns you experience, where you live (although, I must say that we have had more humid days here in So. Cal. than I recall), I think your crisp and colorful woven shirts make a nice contrast with these jeans.
I wouldn't even know how to dye something, so I commend you for wanting to tackle this DIY project; or, is Claire flying in with her bag of tricks?
Do you think you would wear red more than white? It's not an easy call, especially since you aren't wearing them. I think white jeans are a classic.
