“She has ideas that she really wants to bring to life, and then we help her bring it to life in our jewels,” Schwartz told Vanity Fair, adding that Swift had a clear vision from the start for the chain peeking out from beneath the dress’s hem, letter charm and all. “It really was her collab with me.”

Situated on Swift's upper left leg was a beaded thigh chain, revealed ever-so-slightly beneath her dress's sky-high slit. It featured ruby heart stones and a glittery "T" initial. According to People, the accessory was custom-designed by Swift in collaboration with the star's stylist Joseph Cassell and famed jeweler Lorraine Schwartz.
