More than anything

Nina helps Greta hang up each item on the hooks in the room. "Alright then then, down to your underthings," she says with a gesture as she starts unbuttoning the shirt and the trousers. "I don't think they'll fit quite right without proper tailoring, but I think we can get a good idea of how it'll look - and it'll give you an idea of how it all feels."

She doesn't balk at the idea of another woman undressing with her in the stall. The Second Army didn't have separate barracks for boys and girls, so they'd all gotten over each other fairly quickly.

When Greta mentions undressing Thomas backwards, she peers over her shoulder and gives a wink. "Just like that."
