Burnley Grammar School

I've heard there are still some schools in the U.K. which require shirtlessness for PE.Which are these?

I attended a northern grammar school in the 1970s and our pe kit consisted of shorts and plimsolls only.

Yes, takes me back. At my school we did all indoor PE shirtless and in bare feet. Only a pair of black shorts was allowed to be worn. Outdoors in winter was in rubgy kit; in summer and for cross-country we were allowed to wear a white vest (singlet) and plimsolls, but nothing more. For summer athletics and track-and-field on the grass we we encouraged to go with a shirt and be in bare feet.

Same for me, I went to a strict comprehensive school in Yorkshire. Indoor PE kit was just a pair of white shorts, no top, no shoes, no underwear.
Outdoor games was a pair of black shorts and trainers but no top and outdoor PE and cross country was white short and plimsoles. We had outdoor PE throughout the year and can even remember being sent outside once with snow on the ground only wearing a pair of shorts.
I wasn't too keen on the cross country runs as we had to run through our neighbourhood to reach a field. You always had quite a few people looking at you, and yes the girls liked that.
Shame they stopped all that, it sure would toughen some of our teenagers up and instill a kind of gentle discipline.

Same for us in our school. We always had to be topless for PE and the girls enjoyed watching.

i attended a Grammar School in Hertfordshire in the 60s and it was the same for us. our games kit consisted of a pair of white shorts and a pair of white plimsolls. All PE, both indoors and outdoors, was performed shirtless. We were also barefooted indoors and outdoors on the playing field. We wore plimsolls for out door PE on the playground, and cross country runs were performed in the same way. This was the case all year rouns and in all weathers. I have to chuckle when I hear of modern schools either having no games/PE at all or reserving it for good weather.

Nice picture, taking me back to my PE lessons, which for us boys were always shirtless and probably much more demanding than today. We even did cross country runs in winter without tops being allowed.
