Whenever I pack for a trip I lay out my clothes by outfit, complete with undergarments, shoes and accessories. I also do this when I pack for my son. I lay out his shirt, shorts, undies and socks and fold them all together.
Whenever we get to our destination I just unpack the folded outfits inside a drawer or on a shelf and he can grab the whole outfit on his own. It makes packing and getting ready while we are on vacation so easy. Especially if I have specific things I want him to wear for certain occasions. Read more here about Packing for Disney.
