Long sleeve white polo shirts where are you?!

[Chrissayeth]

I have looked absolutely everywhere. Every shop under every stone is sold out in my sons size (5-6years) what the hell is going on? Why is there a shortage of long sleeve white polo shirts during WINTER? ! If anyone selling any that are in good condition I will be happy to buy from you. My son's had a growth spurt and the long sleeve ones he has now are too short for him and his school do slips not jumpers so thats why I need long sleeve.

M&S have some in their”easy dressing” range - it this case that means riptape behind the buttons

Tesco had them

These are listed as girls’, but they don’t seem to have scalloped/“pretty” collars, so I am not sure how girly they can be in smaller sizes.

I thought Asda had them in stock online - but I've just checked again and it's only the blue version they currently have.
Try eBay / Vinted.
