Formal night is on you, and you pull out that beautiful outfit only to find it a wrinkly mess. This looks like a job for Wrinkle Releaser! Well, kind of. We will often pack wrinkle releaser/reducer spray, and in a pinch it does help. But if you’ve got a little extra time and a hot shower, steam will work just as well, or better. On the other hand, releaser spray is cheap and easy to pack, so toss some in your bag for emergencies.
