About a year of so back I got a "wrinkle resistant" twill shirt.
The ad says "wrinkle resistant" and it is resistant - but it does wrinkle a lot easier than other wrinkle free shirts I have. I have to baby it when I wash it, take it right out of the washer right after washing is done, and take it right out of the dryer before it is fully dry and hang it and let is dry straight,but it still is not flat.
I found the oxford shirt in the wrinkle free collection were pretty good, but he twill wrinkle free was a disappointment.
A very attractive shirt, but not wrinkle free and not very wrinkle resistant.
My husband always wears XL in LL Bean so I bought an XL in this shirt. It swallowed him it was so big. I tried a Large and the shirt was so small he could barely breathe. It is a good quality shirt but the sizing is really off. Just to be sure I tried each size a second time in a different color and he had the same problems. Everything else we have bought from LL Bean has been a good fit except these shirts.
Bought several of these shirts 2 -3 years ago and the medium fit very nicely. However the ones purchased recently are too tight across the shoulders and my husband does not have broad shoulders. Kind of strange because the rest of the shirt was a bit on the loose side. Had to return them. Too bad because the colors and the material are really nice.
