Well, Chris, I respectfully disagree.
I know Josette's ghost has a veil. The lady in the portrait has a veil if you look closely. I believe Josette's ghost wears the portrait dress. This makes sense since we see Josette descend from her portrait.
SPOILERS BELOW
Maggie wore a veil while in the portrait dress. She wore a different veil when wearing the wedding dress (when she goes to stake Barnabas). That is the veil worn by the skeleton bride in the Dream Curse.

I'm really not obsessive.
I just see it differently. It's only my opinion.
