Here are some promo shots released by ABC for episode 4x05 'Breaking Glass' of "Once Upon a Time." This episode originally aired on October 24, 2014. It is in the middle of the 'Frozen' arc, so we get some appearances from Elsa and the Snow Queen. These are all set in a forest for some reason.
Incidentally, someone mentioned to me that the Snow Queen's attire was almost exactly like her wedding dress, only without the collar. What do you think? I can see it. I don't know if the bridal train like that is still in fashion, but I suppose it could be. I guess they dress more formally on an everyday basis back wherever the Snow Queen is from - you know, like they may have to get married every day. Come to think of it, that Dracula fellow sure dresses...
Ok, hope you enjoy the photos!
