Stopped in a few shops looking for a woven belt to copy Frenchy's bicycle grip trick. Picked up a light tan Aquascutum trench. Single breasted and cropped a bit short (so either it is more recent or it was a forward looking design). Seems to fit slim enough. Only problem is that it is got a fair amount of discoloration around the collar. Obviously it is going to the cleaners...but since it is 65% poly, 35% viscose, would it be safe to go at the collar with shout and a brush (or even oxy clean)? It is permanently proofed aqua 5 and says dry clean only...but would this be good or should I see if the cleaners get it out?
