Also, remember those pendant heart necklaces that everyone and their mother used to have circa eighth grade? I found mine and found it worked with this look because it doesn't really stand out, so you can't tell it's a tacky heart pendant, you only see a silver shape at the end of a long chain!
Button down- my mother's

Heart pendant- Forever 21
Oxfords- my mother's old ones (probably from Italy)
