After my picture in a knitted dress as a child, today a photo of SC (sccollections) and his brother dressed complety in knitwear, from top to toe. They are posing for a ladies magazine "Margriet", the one I once worked for. SC's father knew the photographer who asked him to have his sons as model. SC remembers the photoshoot as very annoying, they had to smile and the clothes they found both awful to wear. I can imagine that, even in 1951 you wouldn't dress like this as a boy, maybe only the sweater but not a knitted trouser.
But I think the photographer succeeded very well to make a nice picture after all, they look so cute!
