You can also try hanging your clothes in the bathroom with the hot water on in the shower.
I have also used this method, and it actually works as well as some of the wrinkle sprays out there, but that still isn't saying too much. I'm not sure which one of them is really effective, but the shower idea is one you can use if all else fails.
I never leave home without my Downy Wrinkle Release. It's the best stuff since sliced bread.
As I unpack, almost everything gets a touch up with the stuff. It won't take out a hard crease, but those little wrinkles it does wonders for. Most of all you don't have to tie up the bathroom, while steaming.
Also it's cheap enough that at the end of the trip, I give any leftovers to housekeeping. That space is used for my shopping.
I have to travel a lot to conventions where we are exhibitors, so wrinkle free is important.
One emergency trick I have used is as follows:
Spray with water (you should always have at least a small spray bottle in your stuff, even if you have to empty something out of it into a cup and put it back later), then use hair dryer and hand to smooth out wrinkles.
Of course, a travel iron is handy, but heavy in luggage you are watching the weight of.
The spray bottles of water people keep talking about work so well in the heat, especially if you put a little Sea Breeze or other astringent in the water.
Fishing bass tournaments in the heat, we ladies use this a lot for a quick cool off before the weigh in or through the day.
Downy Wrinkle Release is a miracle product...it works great. Just spray on the fabric, pull the wrinkles out gently with your hands and let dry. Be careful using the irons onboard the cruise ships, my friend ironed one of her shirts onboard and the iron had a burr on the plate and it pulled a bunch of threads on her shirt. It was so bad, she couldn't wear it.
I have tried sprays, to no avail. I even bought one of those hand steamers, but couldn't figure out how to use it (I am a little challenged!!). Also, it was too heavy to pack. When you hang up your clothes, most wrinkles come out. Linen is supposed to have some anyway. Once you sit down, that's it! I have steamed clothes in the bathroom with the hot water running and that works quite well.
I have had linen dry cleaned (and pressed) on the ship and I found that they pressed the life out of the clothes.They looked very stiff.
If your dress is real silk, don't use a wrinkle release. It might be fine, but silk is fussy. If it is some other fabric, I would suggest doing a test spot in a discreet area. Doesn't have to be wrinkled, just see if it affects the fabric.
Here is a little trick I learned from many years of traveling. Pack a small spray bottle with 2 or three Dryer sheets in it. When you arrive just add water and shake. Srpay your clothes, give a shake and smooth with you hands. Much cheaper than buying the wrinkle release and it works just the same!
Rosie, great idea... and after all the wrinkles are out and the garments are hung up in good condition, then that same spray bottle can be cleaned out, filled with water and a little bit of astringent and used as a body/face cooling spray. We used to do this fishing bass tournaments and it can be a great cooling spray.
