Since Regina is a fan of metallics, this wild-card choice would offer a new twist on the looks that have worked for her in the past. The one-shoulder silhouette of the gown works in a similar way to a strapless one, drawing the eye up, while the colour pops just as well as a bright neon. The dress is by Peter Pilotto, a label that we rarely see on the red carpet but that's on everyone's lips after being chosen by Princess Eugenie for her wedding gown.
