I don’t know as I’m not the op but it could be she’s putting him in girls clothes
There’s nothing wrong with secondhand or hand me downs I have 4 boys and it would have crippled me financially to buy each new clothes all the time when their older brothers were still good as new. Would I have put them in their girly sisters clothes? No especially not if I had enough disposable income to buy my self new clothes weekly. Maybe that’s the point, she gets new the little un gets his sisters hand me downs when she could some bits for him..
