Neon is one of those things, like leopard print and glitter, that can either look classy or trashy, and the line of distinction is often quite hard to define. When I found this dress at J. Crew the last time I was in the states, I found it struck the perfect balance.
On a side note, the art on the wall behind me is an old calendar that I cut up and framed. Don't throw away last years calendars just yet!
