I've never heard that starching makes clothes wear faster, but, really, how long do you want your clothes to last? Must be a man thing. Hubby doesn't care for stiff starch because it closes up the fabric --- i.e., the fabric doesn't "breathe" and you sweat more. This is true. Now that we're civilians and retired, I barely iron, much less starch! I vote with those who say to starch if you like the look and feel, don't if you don't, and don't worry about how long the shirts will last. I suspect we're talking about a starched shirt lasting 4 years and a non-starched one lasting 4 years and 2 months. Give it up.
