if i recall during the episode where vicki walks along the beach and discovers THE PEN she is wearing her hair in pigtails which she never wore on the show itself.
The pigtails are only the tip of the iceberg.
Vicki leaves Collinwood wearing a white trenchcoat, then she's on the beach wearing a black coat, and then she's back at Collinwood with the trenchcoat.
Another glaring wardrobe/location footage mishap happens when David is seen wearing pajamas and a robe just prior to location footage of him looking out a window (to watch Roger drive away) in which he's wearing a jersey, and then he's seen wearing the pjs and robe immediately after.
That they actually managed to have Carolyn come into Liz' room in Ep #275 carrying a kerchief in her hand after she'd been seen in location footage walking on the beach wearing a kerchief is actually the amazing thing!
But, if you join MB and me on our next visit to Newport, and you were to put on a sleeveless dress and don a black wig with pigtails for a stroll on the beach, then... maybe.
Oh, I don't know - it might be fun to reenact THE PEN scene for posterity.
