Today I saw a mom and dad leading a pair of identical twin girls, and don't you know those cute little girls were dressed exactly alike? They made me smile, but my smile melted into a frown, because everything I've ever heard from grown twins on the subject is that you should dress twins differently and encourage them to be their own persons. I have twin cousins who grew up with complementary but different wardrobes; their dresses might have the same pattern, but one girl's color scheme would be different from the other. That seems like a good way to balance it out. Today my cousins are as connected as any pair of sisters, but are very aware of themselves as distinct individuals.
Still, I totally understand the urge to turn twins into a perfect pair. It reminds me of the urge to have white carpet. When I was a carpet cleaner I discovered that every conventionally-minded newlywed bride wants white carpet in her first house. She soon discovers, though, that there is no such thing as white carpet. There is only mottled gray carpet with brown and black streaks. Any "white" carpet you see is simply a preliminary to the inevitable.
