Taylor Swift made a quick outfit change for her appearance at the Brooks & Dunn's The Last Rodeo Show in Las Vegas this week. Before her perfomance, she chose a lilac dress by Contrarian which revealed a little skin thanks to side cut-out detailing, while on-stage she chose to shine in a deep purple Jenny Packham sequin dress. Clearly Tay's having a bit of a purple moment right now! They're both cute frocks but I think I prefer the soft lilac number — girly but still sexy. How about you?
