The Mica is a little off white, and as long as you're careful where you sit, I don't see it being that difficult to maintain. I've posted my pair with a raw hem and knee rips in the past if y'all want a reference. I've thrown my pair in the washer, no issues.
I couldn't agree more with @KVAEIOU. True to size, I'm a 48 and fits like a glove zipped up and looks great unzipped. Wore it this past weekend for what will likely be the last time until it cools down in fall.
@shibafku, I'm the same sizes as you, and I went with a 42.5.
This jacket will have to wait 7 months for it to be cold enough to wear, but I had to at least try it on. Shout out to @slann01 for the review that convinced me to buy it and @Prudy for being so kind to send it my way!
