I didn't realize it until I got a bag of hand-me-downs, but I always pick the same colors for the Trikester - he wears lots and lots of blue! I opened the bag of clothes from a friend and there were so many red things - which, previously, he didn't own at all!
I guess it's a conscience decision because I think blue brings out his eyes and compliments his fair coloring (okay, that sounds really lame...). And I never wear red myself, so maybe that's why I'm less likely to buy it.
Do you always buy the same color clothes for your LO?
