"W-what?!" Xia An was clearly pissed off by Lu Tianxin's accusation, not that Tang Moyu believed her either.
For someone who was familiar with how The Black Nightingale worked, Xia An's red dress was definitely subpar to those Tang Moyu had seen before. It was only natural for her and Lu Tianxin to doubt its authenticity. Given how popular The Black Nightingale was, it wasn't surprising that some started to imitate her designs, but those couldn't be compared to the original.
The empress herself had a wardrobe filled with The Black Nightingale dresses. It was due to the fact that Li Meili liked to use her as one of her muses and always made sketches based on her body type and shape.
For the love of God, even Tang Moyu couldn't understand why Li Meili still insisted on using her as her subject, but being a good friend of hers, how could she deny Li Meili's requests?
