#1-Check the Forecast
Whether it's the night before or the morning of, always check your local news station for the weather report. Temperatures and rain reports have a lot of impact on the way we dress for the rest of the day.
#2-Layers, Layers, Layers!
When you wake up in the morning for those early classes, and there's going to be cool temperatures outside, wear your favorite cardigan or sweater over your t-shirt. Once you go on with your day and the air gets warmer it's easier to shed the layers than if you were to wear a long-sleeved shirt.
Hopefully this is helpful to you all that have problems dressing appropriately with the weather.
