I don’t like parents dressing their kids of the same gender in the same clothes - twins and siblings about 15 months in difference.
Have friends who have nieces, nephews wearing the same clothes all the time. The children are individual, so treat them like they are.
it may look cute but it’s going towards resentment later on. As I have friends who were dressed in the same clothes as their sister as a child and hated it. They do have kids of the same gender. The only time they wear the same matching clothes is school uniform.
