To begin, you'll need to access the Bitmoji app and tap on the gear icon to get into the settings. From there, click on Change Avatar Style and browse through the various options to find the classic style you're looking for. It's like taking a trip down memory lane!
As you navigate through the app, you'll notice the Bitmoji library has a ton of different avatars and styles to choose from. But don't worry, your old Bitmoji is still in there somewhere! You might need to scroll through a few pages, but it's worth it to get that nostalgic feeling back.
