Knitted school uniform - both tops and pinafore skirts. Doesn't really bear thinking about in this hot weather, really.
Were kids really sent to school in skirts this short in the 1960s? I think you'd be sent straight home if you tried this today.
The pattern is stamped by Bellmans Wools, 21 Station Road, Portslade - which is now a Help The Aged charity shop. I wish that I could say that I'd bought this pattern there, in a cosmic moment of vintage knitting pattern kismet. But I didn't. Sorry.
