I am helping an elderly relative get ready for a big event next month. He has a M&S linen miracle suit like this in a charcoal shade. https://www.marksandspencer.com/tailored-fit-italian-linen-miracle-suit/p/ds51759bac8d0330bb412efed0a4145ea6?prevPage=srp#intid=pid_pg1pip48g4r1c4
It really needs to cleaned - the label stipulates no machine wash. Would I be able to put this on a cold wash (or handwash) and drip dry, or does it really need to be dry cleaned?
I often machine wash my own linen clothes, but of course as this is a suit perhaps there's more room for error?
