Reports indicate the quality of the Cacharel pieces is disastrously
bad, unfortunately. (Check out The Fashion Spot forums for more, do a
search for Redoute + Cacharel)
My experience with La Redoute has also been pretty poor. I bought a
pair of flat pointy Menudier pumps from them a few seasons ago and the
sole got unstuck at the tip in no time. I did also buy some items from
the collection Viktor & Rolf did for them last year, which I still
have. Not fantastic quality, but it's Viktor & Rolf, so the design
redeems them.
Re. Liberty fabric, I would venture to guess they're referring to
'Liberty print', rather than 'Liberty fabric'.
I hope I'm wrong though. I look forward to hearing how you do.
