When I went to college, I noticed that students from the South matched their lipstick to their nail polish. It's what their mothers taught them was the prim and proper way to beautify. I always thought it was a little bit much for me, but they definitely looked more put together than I ever did.
The matchiness made me notice the details of beauty products more, and I started to appreciate how nail polish can be an accessory to complement any outfit. Over time, I find that I coordinate it with my clothes more than I do with the rest of my makeup, though. As a general rule, do you match your lipstick to your nail polish?
