@ScottishMouse , I am wearing that very skirt, the green colourway, today. I have worn it with a thick teeshirt and the Toast ribbed mohair blend cropped cardigan and it feels fab. I actually packed this skirt into a suitcase and bought it to Ireland and back (ended up not wearing it there) and then bought it down to Cornwall in a bag and have now worn it without a sniff of an iron anywhere near it so I do think it is fairly hardy in terms of being crease proof. Mind you, I have the navy one and have washed it so I will let you know how difficult the ironing is.
One of the reviews on the website suggests that it looks good with heels and a little jacket too and I bet it does. I think it is a really versatile skirt and I intend to wear the navy one into the office with a cropped Cos jacket and some pumps.
