Sorry if I didn't post this in the right subreddit; I didn't know if this was a HTML question or a JavaScript question. So, I'm making a website where you can upload pictures of your clothes to easily see what's in your messy closet or create a "digital outfit," kinda like customizing a Mii or making an Xbox Avatar.
