This halloween dress has a "Boo" applique design and a  generous 3-tone tulle underlay (in orange, lime and purple to match the colors on the fabric) an original go.fetch design 

. . . it looks gorgeous . . and the purple and lime embroidery bats actually will be glowing in the dark . . . totally cool when the lights go off. 
The trick or treat vest is to match the HK halloween outfit.  Although barely noticeable on picture, the "trick or treat" is outlined in glow in the dark thread so when all the lights are turned off, you will be able to read the words 

.   
I wish I knew how to take pictures of them glowing so if anyone knows how, let me know.
