Looking for design ideas to elevate simple design

Hey y'all, I'm working on designs for my brother's wedding. One of the requested cookies is a dress that is similar to the actual dress. Other than adding in the ribbing in the bodice, I'm looking for ideas to kind of *spruce up* the design that are still true to the actual dress. What are good techniques that subtley elevate otherwise simple designs?

First pic is the beautiful dress, second pic is another wedding dress design I did a while ago that I am planning to use the same cookie cutter for (as a point of reference for the size/shape of the cookie).
