"Okay." Greta says, giving Regan a bolstering nod and then walking her over to the changing rooms. She, at least, is tentatively optimistic. Once they get a better sense of how the dress fits (or doesn't), they can figure out a plan of attack — all of which sounds better and more productive than continuing to paw through the racks in mounting despair. But Regan might not be so confident.

She pauses outside the door to one of the changing rooms, and adds, "Just knock on the door when you're ready for me, okay?" The changing rooms are large enough to accommodate two people, and she thinks it might be better for everyone involved if they have any conversation about alterations in said room, where none of the shopkeepers can see them. It may not be against any laws to buy a dress you intend to modify, but it still feels a bit rude to be blatant about it.
