idk how to vote.. but i do it sometimes.. a lot of the times i will put them in the same outfit in different colors or patterns instead. it doesn't bother me.. not unless the kids are grown.. it bugs me when i see 30 year old twins who dress alike on a regular basis.. (i used to work in retail, and there was a set of twins who shopped at my store regularly and bought all the exact same things and dressed alike and were in their 30s)
i read that it was better not to dress them a like unless they want too, besides it helps others and sometimes even me to know who is who if they have on different outfits
