I have no problem with people wearing a blue gi (I own 2 reversible gis from years ago) but I wear white fighting film gis. Light enough to train in and strong enough for shiai and heavy randori.The only marking is a small logo on one of the sleeves.
I have worn adidas with shoulder stripes before now but I am BJA and they are not so traditional as BJC.
It's all about the person wearing the gi,not the gi that makes the person.

Keep well Guv. Speak soon.
