I did the same thing yesterday. I was also unsure if they'd offer the traveling gown... I assumed if I bought the gown, necklace, and matching cap as replacement parts, it would be quite a bit more expensive: especially if the necklace and cap are part of Felicity's Accessories.

Good call on the undies: I almost ordered them but then decided I'd ordered too much recently. Did use the 10% off code though.
