Need help with light, fluffy cotton fiber filling material

I need to create a similar look to the images pictured here: I’m going for a very light, airy kind of look. In theory I had some approaches in mind. Namely using a volume shader with a displacement map, and noisy bump, but I’m way off the mark when it comes to the reference images. Any ideas for how to texture this? Thank you! FYI here are the results I’ve managed to get so far. As you can see, it’s far too dense. (The filling layer above the blue layer.)
