I'm pretty sure my boy played cricket in his 'white kit' some weeks at STRS last year. Village cricket practice during the week and matches at the weekend meant kit was frequently in the wrong place.
Yes...been there done that
Me adamantly saying they could jolly well remember their white trainers from their school pe kit every Wednesday night, finally failed so many times and I tired so much of hassling the poor school caretaker to let them run in and get them after hours, that I relented and bought a second set, all be it cheapy ones, just for home.
Toady, our gs boys are not tracky bottom wearers either; the coaches do liberally spray any frost victims with deep heat though, ds1 regularly comes home stinking of the stuff! Only when the sports field turned into lakes this year for several months, did the lads get any variation, or indoor training.
