This is a strong signal that Jil Sander is back, but on the whole not the strongest collection. The quality is good--the video demonstrates the exceptional fit and movement of the outwear--but the school girl uniform and calf boots are better suited at Miu Miu. I want something more grown-up from Jil Sander.
But still this is better than Raf Simons. Raf had his moments at the brand but his work immediately pales in comparison to Jil's own. For one, towards the end of his tenure for sure, his presentations were badly edited. Jil's is much more disciplined and thought-out.
With regards to comparisons to Celine, I think Celine was great in Phoebe's debut year of 2010 but after that it's gone WAY downhill. Phoebe isn't a minimalist at heart and I think she introduced too many elements too soon. With Jil at the helm, you can expect a consistent brand.
