I was given a fabulous down duvet dressing-gown several years ago, but I have never worn it because it is pure white and I am a dirt-magnet.
Last night I was sooo cold that I put it on. OMG sooo cosy!
It is pure cotton, except of course for the down and a ghastly pink polyester trim. Can I dye it a rich dark colour (something like purple, because obviously the pink polyester trim won't take the dye) or will dying it harm the down filling?
