I've seen these while browsing and I kinda like them. Fleece looks great for toony suits and can be stylized in fun ways.
But the mouths put me off. If they didn't have the oddly curved mouth shapes, it'd be 100x better. I've seen the same issue on a lot of beginner suiters so I guess it's just a new maker quirk they need to iron out.
The worst thing for materials like that is they risk looking baggy and being very uncomfortable, mainly on bodysuits. So your measurements need to on point.
Anyway...
