We always match, but I do like your idea of red, black and white.
In my siggie there's a pic of our big group all wearing the Disneystore.com shirt of that summer...except for dh, who wore a plain t-shirt of the same color.
He said he didn't want to look "dorky." Hmmm...
Who looks more dorky, one of many, or the ONE who won't participate.
I like the shirts that
disneystore offers in the summer, that you can get matching of adult and kids.
That's what we always get for one outfit of our trip.
Then the rest of the days, we wear matching colors, or sometimes the girls all in one color and the boys in another (like pink or lavendar, and gray).
[The other siggie pics are our "shades of orange" day. LOL]
I don't see a current matching one on the site, but it seems I bought them in July the other times. Sometimes the kids were as low as $5!
Sounds like your plans are coming along!
