No *properly made* item of clothing. 

The cost on these has unfortunately already been eaten. Increasing the price to what a real shirt should cost new (at second hand) does not benefit the slaves that made it, and it will still fall apart in a couple of washes because labour wasn't the only corner cut. 

Dgmw, I think charity shops should get a fair take, and I agree with you that they should not be made and sold the way they are in the first place. But they should be priced fairly for what they are and for the demographic buying them. 

Especially since many people would rather buy new if it's the same price, now you're making the problem worse.
