Hermione was surprised by Narcissa's quick response and with the enthusiasm that she seemed to answer with. It colored her cheeks pink, though she tried to hide it behind her hair. "I do think red looks nice on me, depending on the red," she answered, trying to sound collected but feeling anything but. She thought about making some comment about being a Gryffindor alum but decided against it.
When Narcissa retreated, Hermione saw that the curtain had remained open. She marveled at the curves of Narcissa's body. What she couldn't see, her imagination filled in. Seeing her in the mirror's refelction, Hermione didn't realized Madame Malkin had been talking to her and trying to get her attention. "Oh, sorry. Ummm...usually I prefer things with a natural waist," she answered the question she had missed.
Hermione liked Narcissa's idea, mostly because the idea of showing off for her was a pleasant one. Feeling heat pooling between her thighs, Hermione was hoping she wouldn't need to get down to her bra and knickers in front of them!
"That does sound...nice. A little more adventurous than I normally am but that could be...fun?" Hermione mused, a little more suggestively than she had intended.
