Like most of the other posters, I use Packing Cubes and rolled or carefully folded clothes.
Most of my trips have at least one dress up event. One trip was precisely timed to get us from the airport, to the hotel, our room to freshen up and dress up then drive to the venue without a minute to spare.
Under those condition, un-bundle packing the dress clothes and accessory would have been very unwise as it is very time consuming, time, we didn't have.
The Packing Cubes performed flawlessly, the dress clothes, some ironed at the departure point, unfurled with no need for ironing touch up.
To speed up the dressing up process, I only took out the Packing Cubes, unzipped them, laid out my husband outfit and proceeded to get into mine, add accessories and makeup, grab my dress bag along with the direction to the venue for the event which was scheduled to start very shortly.
Car GPS, phone map, and the bride very detailed written direction to the rescue and we made it.
I could not have pulled off many fast and necessary wardrobe changes from comfortable traveling outfit to good looking dress-up without my Packing Cubes, as a result of their flawless function, I bought more in different colors and shapes.
I know that I am not alone.
I did try bundling versus Cube packing while doing practice packing, un-bundling in a hurry always resulted in a messy pile from which each wardrobe piece needed to be extracted from, inspected and more often than not. needed extra ironing.
I don't appreciate doing the same chore twice (ironing), it delays the setting up of each outfit in the room dresser and steals away jet lag adjusting rest as well as primping, socializing and new horizons enjoyment time.
