Eeek! I've turned into my mother! i don't wear white this time of year. Once school starts, it just seems like white is no longer appropriate and the temperatures are just too erratic. For instance, today it is 85 degrees and warm, If it weren't so windy, it would be a beautiful summer day. However, last Saturday night we went to dinner with friends and it was too cool to eat outside on a rooftop (and I made sure I was dressed to stay warm and had a wrap).
Living in a four season environment, I have come to the conclusion that the hardest months to dress are April/May and September/October.
