I think that the new costumes should be like this:
Mal - Green leather jacket with magenta spikes, black t-shirt, dragon necklace, purple jeans and black boots with magenta spikes.
Jay - Yellow-crimson t-shirt with zipper, light blue-dark grey pants, snake bracelet and black boots.
Evie - Dark blue jacket with golden crowns, blue-red dress, golden crown and brown boots with blue spikes.
Carlos - Black-white ripped hoodie with red details, black jean shorts, golden dog tail necklace, red-black sneakers.
