I chose this simple black dress that I found last year. I bought it at full price and have worn it one other time. My friend, Sarah, always sasses me... asking why I never wear my black dress since she hasn't seen the ROI on the amount I paid and the amount times I've worn it :). Second appearance = totally worth it.
