DVF wrap dresses - viscose?

[CaroleService]

When did this happen? They were always silk jersey before (and the price hasn't gone down!)

Anyone got one and can reassure me it keeps its shape, doesn't wear, etc?

(And can be quietly washed ...)

Is it a plain colour? I noticed when browsing on the DvF website a while back that the plain black dresses seemed to be viscose and the coloured prints were silk.
Do you hand-wash the silk jersey ones or always take them to the dry-cleaner? Alas I have no experience of how DvF dresses of any sort wear.

It is black and white print.

I have hand-washed a silk one before; all ok.

I've also noticed the patterned ones are still silk but the plain colours are viscose.

I was looking at a DVF dress in a charity shop today for £45, hadn't heard of them. It was silk jersey but not wrap style. A kind of dropped waist with a fabric belt in same pattern.

Worth buying I wonder?......
