Selena Gomez just redefined holiday party goals! She showed up to support Amanda Seyfried in LA rocking a killer asymmetric little black dress by Jacquemus, dripping in Tacori diamonds (those earrings alone are $26k!). Both Selena and Amanda proved the LBD is the ultimate party staple—sleek, chic, and always in style. Anyone else suddenly feel like shopping for a new dress? #Beauty #SelenaGomez #LBD
