This is what you might be wearing if you were a little dude in 1960s England off to church on a Sunday morning. You would need to team it with a buttoned up shirt off course and some very long socks to stay warm. Possibly even a smart cap.
More clearing out of Grandma's house has unearthed this little suit that belonged to my partner when he was the same age. Do you think I can coax him into wearing it for Grandma's 90th birthday party???
