I like the idea of Atlein...This kind of Nicolas Ghesquiere's revival or nostalgia with a cast of women, something very sexy and subtle.
I mean, even Nicolas's fit model at Balenciaga is there...
But i don't think this is enough to have your own line.
This doesn't have that extra dose of personality. So maybe he can be better working for another brand or simply as a design director or something because his voice is not loud enough.
