Rebecca is wearing a chiton-style dress, cinched up in the back to accommodate her wings. The shiny, satiny fabric is blue marble patterned, with some gold veins restrainedly threading through it. Her wings are blue-white with golden edges on the flight feathers and her hair's up in a loosely ancient Greek style with gold frost-on-glass patterns holding it in place instead of laurel branches. She's wearing blue sandals, also loosely Greek, and there are some gold frost ornaments on those too. The pins at her shoulders holding her dress in place are also frost-flowers in gold; the belt around her waist is just a gold chain with lapis lazuli beads, though.

Mr. Peale pulls out a notebook and starts making sketches from various angles. "I like to get something on paper before I start making changes," he says apologetically. "Do try and stand still. Have you tried using the frost-pattern on your dress instead of the marbling?" 

"No, I haven't been magic very long, I haven't tried that much stuff."

"Try that - actually, let's get the silhoutte down first." 

He has her run through a dozen or so variations each on the height of the waistband, the drape and gather of the fabric, the neckline, and the length of the train. 

She holds obligingly still. "Can I frost your window to see how it looks?"

"Go right ahead. Of course, you can work on a much finer scale." 

She frosts the window. "I haven't done any clothes stuff with a lot of frost pattern, just the little bits for the jewelry." She studies the window and then shuts her eyes and tries replacing the marbling. It doesn't come out all that well. "It's about the same," she says, opening her eyes.

"Try -" he starts sketching again "something like this pattern, in pale gold, lines half as thick as what you've got now." 

"Instead of the blue?"

"Try the gold first. I want to do something about the blue anyway, this shade is adequate but uninspired." 

She squints at his pattern and changes her dress. "Yeah, it likes that better."

"Now change all the gold in your outfit to match that shade." 

That's easy. "It likes that too. Huh."

"The magic, like all great artists, appreciates unity of composition. It's happiest when the different components of your outfit match. In this case I thought the paler gold would set off your hair better - try growing your hair longer and weaving the gold through more of it." 

He's sketching furiously throughout. 

"- yeah, it likes that."

"Hmmm." He leans out the window. "Mrs. Copley! My sample book!" 

While they wait for the sample book, he has her change her belt to the same frost-on-glass pattern, experiments with various layers of necklaces, armbands, and bracelets, adds frost-flower earrings, and asks her to outline all her feathers in gold. 

"The belt pokes me in the stomach when I breathe like this." The other experiments are fruitful.

"Make it white leather with the pattern embossed in gold." She's wearing three necklaces of various lengths and a pair of matching armbands. 

"That's not as good magically but it's comfortable."

"Your choice. You can always change it out if you need the extra power during a fight." 

Presumably-Mrs.-Copley shows up with the book of fabric samples. He flips to the section on blue and has her cycle through 47 different shades. "And while you're at it, can you make the material less  - glossy?" 

"Yeah? I was going for polished marble first but I guess it's not marble any more." The fabric calms down by slow degrees.

"Stop when it starts to hurt more than it helps." 

She stops. It's still a little shiny but not nearly as much.

Once they've found the optimal shade for the dress, he asks her to make her wings a gradient from that blue to white. 

She does. "- doesn't help."
