Lilly Pulitzer Finley white lace V-neck dress Small

Lilly Pulitzer Finley lace V-neck dress Small. Only worn once! Never washed. It runs big!!! Fits more like a medium or large. I am looking for an XS. I typically wear a 6 in most things. I was planning on including the white slip dress shown in the photos (size medium, from Fashion Nova). For reference I am 5’7, 130 pounds, 34C, 28 inch waist 38 inch hips.
