For the YDY Mobile Fitness Game ( https://www.ydylife.com/ ), I was also responsible for creating assets for Character Avatar system (Modeling, Texturing, and Rigging).
Overall, there were 6 different categories to pick and choose from: Bottoms, Extras, Eyes, Hair, Shoes, and Tops. Additionally, each accessory usually had around 2-4 color variants, and most were designed to minimize clipping with accessories on other body parts.
