Costume designer Mark Bridges chatted EW about Jen‘s, 23, lack of fear when it came to the costumes in the flick.

He shared, “We [made an outfit] with that same shape [from rehearsal footage], adding sparkly lace and sleeves because that would be the kind of thing that Jennifer‘s character would have done.”

FYI: Jennifer is wearing a Dana Rebecca Designs ring.
