Buying secondhand is a great way to not support the made in China machine. All the clothes we have bought for this baby have been pre-loved.
I know some people get funny about second hand clothes, but I find that weird. You'd happily sleep on hotel or hospital sheets that have seen hundreds of different bodies, and then been washed, but won't wear clothes that have done the same? Doesn't make sense to me.
It's also just a great way of saving (environmental) resources, too - regardless of where you buy them from - because babies grow out of stuff so quickly... I asked for no clothes for T, because we already had heaps given to us when S was born, and still we got clothes given to us as presents (and I'm ashamed to say some of the new stuff, she didn't even get to wear, because by the time we got round to it, she'd grown!)

I'm not sure what your friend/social networks are like, but for both babes we had people falling over themselves to give us clothes for free. I just said 'yes' to everything and sorted through them - anything I didn't want, I just packed up and put in a Vinnie's or Good Sammy's bin. And it's not like we're really popular people with loads of friends if you put the word out to your family or workmates, you might be surprised the number of people they know who want to get rid of clothes!
