" What a pretty dress,” Ariadne said to Cordelia, her voice warm. Her own gown was of flattering wine-colored silk. “I believe that’s the shade they call ‘ashes of roses.’ Very popular in Paris.”
“Oh, yes,” Cordelia said eagerly. She’d known so few girls growing up—just Lucie, really—so how did one impress them and charm them? It was desperately important. “I did get this dress in Paris, as a matter of fact. On Rue de la Paix. Jeanne Paquin made it herself.”
She saw Lucie’s eyes widen in concern. Rosamund’s lips tightened. “How fortunate you are,” she said coolly. “Most of us here in the poky little London Enclave rarely get to travel abroad. You must think us so dull.”
“Oh,” said Cordelia, realizing she had put her foot in it. “No, not at all—”
“My mother has always said Shadowhunters aren’t meant to have much of an interest in fashion,” said Catherine. “She says it’s mundane.”
“Since you’ve spoken of Matthew’s clothes admiringly so often,” said Ariadne tartly, “should we assume that rule is only for girls? "
