The rules of fashion don't apply in these easy-breezy times. Wear colors that don't go together in nature and see what happens. Wear as much color as you can stand and it's OK.
I began to feel this fashion freedom last year when I splurged and bought pairs of shoes that were mint green and dusty rose with blue trim. Short of some old sandals I may have worn as a child, that's the first time I have worn colors on my feet that weren't fashioned in classic (blah) colors -- black, brown, navy etc.
Then, I really went wild, and bought some white sandals to wear to a summer event. I can't remember the last time I owned white shoes. It might have been for First Communion.
August is here now and for the first time in years I am not anxious to see summer go and make way for my favorite season -- fall. That's only because I want to be able to wear my groovy footwear longer. I even want to be able to break the No-White-Shoes-After-Labor-Day rule and wear my new sandals on a trip to Nevada early in the fall. It's got to be summer in Nevada all year, right? That's what I think too.
