To make dress cookies you'll need:

Outline and flood the dress in the base glaze color.

Allow to dry for at 30 minutes.

Take the end of a clean paint brush and press folds/creases into the dress.

Also add some smaller pleats/creases to the sleeves.

I used a cake tester for this.

Once the base has dried for a while, you can add any accents.
There's so many posibilities!

Here's some cookies to celebrate a sweet girl.
