Well, yes, if the home shirt is blue and white stripes it will be satisfactory. Anyting else would be pants.
The away shirt is OK I suppose - but should only be worn when there is a genuine clash with the home team's colours that might cause confusion. So not required against Lverpool, United...
Oh FFS! It's a shirt! A f***in' shrt! A f***in' football shirt. In terms of global politics, the refugee crisis, the war in Ukraine, the price of fish, the advancement of LGBT issues, Brexit and the Schleswig-Holstein question, it means f*** all.
Blue and white stripes. It's not rocket science...
