This article contains wonderful images of YSL clothes and drawings, as well as the beautiful museums being built to house his archive (http://www.vogue.co.uk/gallery/suzy-menkes-pierre-berge-ysl-should-fashion-legacies-be-controlled).
The article is misnamed somewhat: Suzy Menkes only arguing that the museums need to offer the context in which YSL’s creativity flourished. This might be right but I imagine there are arguments for showing in an uncluttered way the range of a designer’s imagination and change. Menkes does not address the question whether all editorial decision is control or who or what qualification garners control. Minimally, we can say that Edmund Burke would welcome these new institutions of Establishment.
