So I bought this avatar off of the SL marketplace, https://marketplace.secondlife.com/p/BlunderForge-Black-Appaloosa-Stallion/5273741 and it seems to work fine except the legs everything below the knee is just black instead of that frilly white, it really detracts from the avatar, I put it together properly and I think it has something to do with something called "digigrade legs"? Can someone please help me, I'm like super new to SL so try to be as lamen as possible.
