I go to M&S and Heatons. My son is majorly hard wearing on clothes and got 2 years out his M&S trousers and they were only 12 euro for the 2 pairs, so very happy with them.
His shirts came from Heatons and he got 2 years out of them too.
Very happy with both. Not mad on Tesco stuff, it does not feel as good and does not last as well. Got some stuff in Dunnes last year too but the trousers were massive on the waist and there were no buttons to make them smaller, so ended up taking them back!
