I've been a bit worried about getting all the creases out of my chiffon dress as the garment bag was too small (I now have a new, bigger one).
I had read about using the shower to steam it and decided to see if it worked a few days ahead of time.
It only took about 5 minutes with the shower on hot. I turned it off and then just let the dress stay in the steamy room for about 30 minutes, rotating the dress once halfway through. And it's perfect!
I was worried I would need to purchase a steamer so this was a happy discovery for me and thought I would share.
