I wonder if her mum dressed them identical so she thinks this is what she has to do and makes it her version of a family. She needs a therapist to unpick her very strange waysIt’s because she’s a bleep. Hope that helpshhh.
On a more serious note, the most probable reason is:
She has no ideas, personality or imagination of her own so she’s perpetually projecting this lack of personality on her children so they never see themselves as individuals in the future. Therefore she dresses them the same so they grow to believe they are part of one thing, and part of one brand.
