Is that photoshop or make-up? It is full-body make-up.
What do you use to color your skin? Custom-blended "Ben Nye Color Cake Foundation." I use a combination of 3-4 different colors to create the necessary effect for both Princess Bubblegum and Karkat Vantas.
Where can I get some of this magic make-up? I buy mine from a local store but you can get it online with a bit of ebay or google searching.
Are those jewels on your face? Are your eyelashes pink? How big is the dress/How do you make it big?? Yes, yes, and delightfully huge via a three-tier hoop skirt. <3
