New Fashion Aesthetic

I’m read­ing De Botton’s The Archi­tec­ture of Hap­pi­ness at the moment. Its dis­cus­sion of the things that deter­mine taste has lead me to won­der what it is peo­ple find appeal­ing about the New Aes­thet­ic. A lot of the dis­cus­sion about it is very cere­bral. “What is it?” etc. What I’m inter­est­ed in is: why do we find it inter­est­ing / beau­ti­ful / etc. Because after all, “There are as many styles of beau­ty as there are visions of happiness.”
