<p>I have MZ boys and I dressed them alike almost all the time until they were about 2 or 3yo, when they started dressing themselves. I thought (still think!) it's so cute to see twins dressed alike and I knew that I only had a certain window before they'd make all their own clothing decisions.</p>

<p>Now that they're older, I'll buy pants in pairs, but I buy shirts in singles and they typically divide them up themselves. Each boy has a favorite color, and he will usually "claim" that color shirt, or at least will wear it often enough that I consider it "his" shirt and if I see his brother wearing it, I'll ask why he's wearing his brother's shirt.</p>
