Vinnies. Lifeline. Salvos.

Places like Target are usually copying particular fashion styles in a need to get it out there fast, and at a lower price. They send huge orders with harsh deadlines to their manufacturers who fall all over each other trying to get the big contract, and workers end up pulling double shifts in terrible conditions to make it.
The on-flow effect of this is that they don't make em like they used to. Second hand garments shipped to Africa, Asia and South America (you think they end up in Vinnies when you throw them away? Only 5%) are now far less re-saleable because of reduced quality, so end up being thrown out. Not a winner for the planet.
