Short pajamas/home sets

The grey one seems to not have been worn, the orange one maybe a couple of times. The Baby Shark has been worn more, it's in good condition, although there seems to be a stain on the collar. I can include the other Baby Shark, there's a visible stain on the shirt, not sure where it's from, it might be washable. They've been in the closet for some time, so they're not ironed and need to be washed again.
