Silk. I can't say any of my silk blouses wrinkle.

I neglected to say I don't iron any more. I made the decision to take all my blouses to the dry cleaners. I strive to get five wearings between cleanings. So far this has worked well but summer may be another story. In the summer, I tend to wash everything after a single wearing.

And like Joy I do a load of wash nearly every single day. It keeps everything manageable.

Interesting to read all the responses here. Had to think this over.

Wrinkled is a fact of life for me. Being a dressmaker, I actually quite like ironing, but even the crispest fabric will collapse like a paper bag as soon as I put it on, so I've more or less given up.

I think this is one of the reasons I'm so passionate about quality materials. If I look rumpled, I'd like to look elegantly so. For me, the character of the fabric is secondary: inexpensive linen creases as badly as anything else in my opinion. On the other hand, I've found that more or less any fabric of sufficient quality will keep its shape and wear the wrinkles well.

I'm pretty sure this is why I keep going back to t-shirts too. Much as I love a nice button down, I know a top notch tee will never fail me.

I have zero tolerance for wrinkles, so I've learned to embrace ironing and have come to even enjoy it. I even iron my t-shirts....

I LOVE ironing for some bizarre reason. I find it almost meditative and the results are quick and lovely. But I don't spend a lot of time on it nor am I a lover of "crisp" on myself. Though I have always loved how "crisp" Carolina Herrera is as Angie.

So I don't like wrinkles but I don't want starched or crisp. So I have started steaming. Or I do a quick iron with particular attention to collars and sleeves. I also iron t shirts unless they are drapey, then I steam them.

I don't hate ironing but just don't want to make the time so I avoid it and rarely iron. My cotton tops don't get worn a lot because of that but most other things are OK, I do wear a lot of knits and blends. A good friend of mine brought her iron when our families went camping, and she actually used it! I was astonished. She irons everything.

I actually like ironing! But I hardly ever do it. In fact I couldn't find my iron last month when I went looking for it... I think one of my sewing daughters made off with it.

It helps that I am pretty RATE and don't mind a bit of the rumpled look; nothing stays pristine or polished on me for long. But climate is a huge factor too. We live right next to the ocean, and it is almost always damp and cool (compared to other places in the same season, I suppose). So even if something looks wrinkly when I take it out of the closet, by the time I get where I'm going, the wrinkles have all fallen out, except for the new creases from wear. And those, in turn, are minor compared to the humid heat of a southern Ontario summer.

It also helps that M. Abeille takes his shirts to the cleaners. That was begun due to a problem with iron staining from our water supply. Before that, i shook them and hung them up directly out of the dryer on permapress cycle (as i do with mine). Or before that, when we lived in Cape Town, hung them on the line, and the "Cape Doctor" (strong local wind) took all the wrinkles away, and sometimes the clothing along with it!

I can't stand to put something on my body that is wrinkled, but it doesn't bother me at all the way linen and tencel wrinkle during wear. I do despise the way viscose and thin rayon wrinkles like crazy and won't buy those fabrics, even though that sometimes requires walking away from something pretty.
I don't love ironing, but do it while I watch tv. I always have an "ironing show" cued up. Right now it's Frankie and Grace - silly and not enough of a plot I need to pay close attention.
I wear a lot of silk tops and I hand or machine wash on delicate (yeah, I'm a big risk taker!) and then steam. So times I need to iron them a bit at the bottom.
Anchie, am I remembering correctly that you wear a lot of fairly formal business attire? I think you'd love a commercial model steamer if you have space. We bought one over a decde ago when we both wore suits everyday. That baby paid for itself in just a few months because we were able to take things to the dry cleaner less often. It is still going strong and used on a regular basis.

I dislike ironing and would prefer to never have to do it. When I wash I shake the heck out of my cotton and linen button-up shirts and hang them to dry on old pantihose to reduce wrinkling. I smooth down the overlaps between my thumb and forefinger to flatten the band/facing. I put the shirts on to hangers off the clothes line. I interline my skirts and pants to reduce wrinkling. Most of my wrinkles come from driving in the car to work.
Best wishes to all.
