I don't have an adult ghost, but these are yearlings. There is a considerable amount of variety in ghosts though, so yours might not end up looking like mine, but just to give you an idea.
BTW, Selene, the one on a blue sheet, shed about 2 days after this. I must have missed her blue phase - but I thought she looked kinda dull. It can be hard to tell that the ghosts are in shed. Now my normal, from about a week BEFORE she goes blue until she gets out of that old skin looks just awful. :shrugs:
