I'm a firm believer that a lot of season rules are a thing of the past. Go ahead and wear florals year around if you want to. I'm more into dressing for how the weather feels. If it's dreary outside, then I dress with that same feeling. With an ugly overcast day, I decided burnt orange and olive green felt right.
It was warm and ugly when I went out this morning but currently it's snowing. It's always great when the weather decides to change on you so you're not even remotely dressed weather appropriate.
