Outfit and color references sheets that I use! Cause I got tired of google searching everytime I need reference... and hopefully now, it can help you!

Most of Images are taken from the Steven Universe Wiki. Seriously, the wiki is amazing, check it out! Individual links of mains below; you can see which episode the outfit is from. Some characters, like Steven, have tons more outfits, but I just included the ones that I liked the most. ^^
