When I was in high school my best friend and I used to call each other before going to a disco or a party to see what the other was wearing. Then we would co-ordinate in similar outfits :)
We always had a similar style and when getting ready for a night out in our 20's we used to call each other beforehand as well but this time to check that we were NOT wearing the same thing. (this came about after an embarrassing night out in matching jeans & tops!)
While reading Grazia the other day I saw sisters Jess & Stef Dadon attending Paris Fashion Week wearing co-ordinating clothes.
I kinda liked it. Not that I'll be doing it anytime soon ;)
How about your kids? Are you ever tempted to dress them in matching clothes?
I admit sometimes on occasions I will dress the boys in all the same colour.
