Yeah, we have a dress agency/consignment shop down the street from us. I like having it nearby, and have been able to offload some stuff and make some money back. It's also located next door to a charity shop, so if I do go to the consignment shop, I try to make sure I have a bag for the charity shop to keep the karma levels nice and even

But actually, our consignment shop will donate whatever hasn't sold in a few months anyway, so at some point, it will go to charity.
I'm more of a high street shopper (gap, banana, etc) so usually I just try to donate straight to the charity shop as the consignment doesn't want anything that's not a fairly expensive label to begin with. which is fair enough! I've got some designer stuff, but I mostly want to keep it!
