^^I wouldn't say there's any direct look-a-like, but the general proportions seem to feel referential to what Phoebe has been doing at Céline recently.
But, in my opinion, unlike Céline, there is never an easy or believability to what Proenza creates. Sure, sometimes it can be stylish or read as "cool," but to me, and especially seen on the sales floor, there is a generally heavy hand and poor fabric selection. They are simply too self serious for my taste. They talk a big talk....their inspirations are always so lofty, obscure and pretentious, but then their work tends to be a pretty one-dimensional, surface level interpretation of said inspiration. There's never any real nuance going on here.
