Taylor Swift Inspired Sequins Lavendar Party Gown Dress Girls XL 170 CM US 16

my daughter bought this dress for a Taylor Swift themed dance party and only wore it once. it's size 170 cm, which is about a girls US size 16 or XL. This would also work for an adult XS. please see 2nd photo as there are a few sequins missing towards the neckline. it came like this and is not noticeable on! the dress comes with size 11/12 hot shorts. they are stretchy so she bought a size down in those. please see photos for measurements thank you!!
