Extra details you might require for your decision: It is 10 degrees outside. The pants you wore today are jeans. Your workout consisted of an easy 2.5 mile run. The bus ride is only 10 blocks, but you will probably have to wait about 10 minutes for the bus. It is not very windy. If you would like any other information, I have constructed an elaborate hypothetical environment for this question, so feel free to ask me in the comments section.
