Both reactions satisfy Valentina enormously. Tatiana's as it's nice to have a fellow professional (especially one not in direct competition), agree with your choices and Erika's admiration is always a delight. Valentina doesn't speak french, so the meaning is lost, but the tone and the rapt expressions are not.
Moving to stand next to Erika she smiles her delight at her lover and slips an arm about her waist.
Replying to Tatiana she asks interestedly 'Oh, do you think so? How many strings would you advise for such a necklace?" Valentina's curiosity is peaked as she'd been considering changing the neckline on that gown.
