Picked up a pair of these during the 20% off promo at the weekend. It's the first pair of trousers I've tried in ages that vaguely fit my post weight loss body, although I'd still need to get them altered slightly before they get an outing. Also, for the cost I'd like to think I'd get away with wearing them a few times. Do you think a) I could get away with wearing something like this to work in a smart/casual office? And b) that they could be machine washed (the website says dry clean, but it's a 98% cotton velvet with no lining...)?
