What to Wear to a Taylor Swift "The Life of a Showgirl" Release Party (and Eventual Tour)

Topdress Halter Retro Cocktail Dress ($37)

Slip into this deep-purple halter dress, and you'll be transported back to the very first time you saw Swift perform live — especially if you attended the "Speak Now" tour, where she donned a similar cocktail dress and belted out romantic ballads like "Sparks Fly" along with heartbreaking hits like "Dear John." If you're lucky, she might even include a song from that enchanting era in her surprise setlist for the concert.
