Here's my rant to add to the pile
Disposable fashion is not OK!!!

It is morally irresponsible to buy something that will have to go into our burgeoning landfills after 1-3 wearings. I personally think hard about ever buying from a brand again if a piece I've worn alot is unwearable after its first season. Clothes should last for years, and jewelry should last even longer. Even good costume jewelry really lasts ... I have a Ben Amun necklace (very similar to something Chanel has for fall btw) I bought about 15 years ago that's still perfectly wearable.
It's extremely enlightening to go to a city council meeting where the people who actually live next to the city landfill are testifying about what it's like. Trash is nasty, and we need less, not more.
