Hermione immediately saw areas where the dress needed to be altered in order to fit Luna perfectly. "Hold still and I'll fix it for you," she stated wanting to ensure that the dress was indeed a perfect fit. With a few flicks and some swishing she spoke the incantations that made the necessary corrections.
"There," she folded her arms and gave the other woman an appraising look. "It looks absolutely splendid on you." Hermione didn't mind giving up a dress for Luna. It was the least she could do after the other witch had helped care for her without reserve in the days following their time at Malfoy manor. Luna's strength amid her own turmoil had amazed Hermione.
