I made Mickey head tie-dye shirts for me and our four kids. For my husband, I got him a bright green shirt and put "I don't do matching shirts" on it in Mickey font. He really didn't want to wear matching shirts (obviously). Well, he got a TON of attention wearing that shirt. It was too funny. One CM was very insistent that we go into the hat shop and at least buy him a tie dye hat, because he really couldn't be with a tie-dye family and not wear anything tie-dye (we didn't, but it was a fun conversation).
That was the only day we matched (well, we wore them twice on the trip), and I have to say it was so nice to be able to easily pick my kids out of a crowd.
