The question is calm enough that Regan forces herself to settle before answering the first thing that comes to mind — which, in this case, is a knee-jerk but unhelpful It's ugly!. It's not an ugly dress, is the thing. It's just that the bodice is sequined in the wrong pattern, and the skirt is too long, but the color is perfect. She tries to relay that to Greta as clearly as she can, without looking like a total maniac in the process.

It's never escaped Regan's notice that Greta wears clothes for utility more than for fashion. And for a long time, so did Regan herself. It hasn't been until recently that she's even allowed herself to wear clothes with fabrics that she knows will make noise against each other, even if she can't hear them herself. Maybe bringing her mother-figure prom dress shopping is weird, but all of her school friends have had their dresses on reserve for months. Greta might not be the most fashionable person in Darrow, but she is still good at clothes, knowing how they fit and drape and work, and Regan wants that knowledge and help today.
