Dubai, adjective

It looks like the word Dubai is officially being used to mean bling:

So people want to look understated?
Yes, I don't think anyone is going to want to look overly flashy, overly glitzy, too Dubai, whatever you want to call it. I just don't think that's the moment. But I do feel an emphasis on quality and longevity and things that really last.
