Of course!!
And I didn't mean that you should wear what you normally wear off the bicycle, but rather to wear whatever makes you feel comfortable when you're on the bicycle. In other words, if it is a really hot day, wear a light jersey (without a baselayer) with a long zipper to unzip to get a decent airflow. If it is a cooler day, add a layer.
The only time I break out the baselayers is when it is quite chilly out there ... unless you call a sleeveless jersey worn under a shortsleeved jersey a baselayer.
