Thats a great point. I used to own so many iron free shirts. I got used to wearing shirts being so easy... Wear, throw in washing machine, then hang dry, and voila ready to wear (or at least enough to add a sportscoat and hide wrinkles until they disappeared on their own )
Problem is, they are I'll fitting being cut for older men ( even my seidensticker shirts at 90euros each).
So I bought suitsupply shirts, great but buy after the first wash, oh boy.. forgot all ironing skills so ended up going back to my older shirts (that to be honest held up so well, until a few started rippng at elbows.. I did wear them 8+years - I do have a lot to rotate through tho).
Then I discovered Spier Mackay and love their shirts too but indeed it's the same problem, a lot of Ironing is needed ...
this is an amateur (but genuine question
BB and Charles Thyrwit both make acceptable to me non-iron shirts in slim fits.Brooks bothers Milano non iron does well for me. I don’t find the feel of cotton to be so inferior to non-treated fabric. I think they have come a long way. I am also a fan of cotton/tencel or cotton/modal mix. But no poly for me. They are hot the moment I put it on. Poly anything makes me sweat. The whole thing about sweat wicking thing only applies to me if I’m wearing that garment to play 18 rounds of golf in 90+ deg weather. YMMV
