Daum in response to Lam stated "To everyone causing so much negativity: I mean no disrespect to the Chinese culture. I’m simply showing my appreciation to their culture. I’m not deleting my post because I’ve done nothing but show my love for the culture. It’s a fucking dress. And it’s beautiful." 
An article in the South China Morning Post interviews people living in Mainland China who praised her wearing the dress.
