Nina looks so thrilled by the prospect that Greta can just about convince herself that it would've been mean-spirited to refuse. And really, a pleasant distraction couldn't hurt. Just because Nina isn't a puddle on the floor, that doesn't mean she isn't having a hard time.

None of those things are enough to magically transform 'letting Nina spend an absurd amount of money on her' into an act of pure charity on Greta's part, but at least it helps allay the discomfort she had with the idea.

So she grins, even as she starts to change back into her own things, passing Nina first the waistcoat, then the blouse. "Oh, you should!" she says, both because Nina ought to get something out of this besides satisfaction, and because the whole thing will be more fun and less intimidating if she's not the sole focus. "Then we'll both have something to show off at the end of it."
