Nice tartan Downunder, and the pleating, save for the wrinkles, looks good too.

The wrinkle condition is certainly not perfect, but not huge. like others have said, I too have had wrinkles that bad after a few hours drive time. What worked for me was to give it a steam while pulling a bit of pressure on the bottom of the pleats in the direction away from the wrinkles. Don't get greedy and try to get them out in one fell swoop. Apply a little pressure while steaming then let it hang a while, if it's wool they will come out no problem. If they don't come out after the first steam and hang, give it another go the next day. You'll be fine.

Good luck!
