This is 50% how you iron the shirt and 50% the shirt itself. Depending on the materials the shirt is made with, shrinkage of the thread and cloth fibers as a result of the first wash will remove any chances you have of making the shirt look like new. If you're lucky and get a shirt that washes well, everything else has to do with how you iron it. Typically, steam on the appropriate temperature setting will make the shirt look like new. You just have to watch how you go about refining creases and keep appropriate tension on the fabric. Some people like to use starch during the ironing process, but it causes the fabric to look unnaturally stiff.
Thank you! Too much of a science to my mind. I can calculate primes from 1 to 101 under a minute in my head, but the finesse of cloth ironing will delude me forever. Easier to get your wife do it for you or just buy a new shirt.
