On the avenue

Today I snapped a picture of myself in the shiny window of a building on fifth avenue. I had just come from a meeting - hence the shirtdress. I was meeting people who I had never met and was a representative of my company so I wanted to seem smart. Even though this dress makes me feel naked on the bottom. I need to find a way to fix that, any ideas? I'm thinking if I can find a pair of short knit shorts or leggings than I can put that under it and I won't feel so exposed. If only this dress was an inch or two longer.
