My wife is about to get her road bike for Christmas and knowing her, she's gonna want to ride it asap. However, it'll be in the mid 50's here in Houston for the next 4 days. We both have lightweight convertible jackets, but that's really about it. So, aside from the jacket, what else do we need to be comfortable and at the same time look like and feel like "real" cyclists (i.e. no parachuting shirts, etc.). I already got us some gloves and a couple cycling beanies at Performance Bike, but have no clue what we need on our bodies (base layers, jersey, etc.).
