Inspired by the Chinese running gear scene, turns out there's a whole bunch of stuff on Taobao available which generally seems to look pretty high quality. Great if you're in a country that Taobao ships to directly (like Aus/USA/NZ/Canada). Easiest way to shop on Taobao is through the app. Your language in the app has to be set to Chinese for most of these shops to appear.

Here's what I've found so far for higher quality gear:

That took a bit longer than I thought! Heaps of really interesting looking options though. Bad month to be a credit card 

you can use a service like superbuy to buy from taobao if you're in a country it doesn't ship to, since cycling clothing usually is pretty light shipping shouldn't be outrageous, i recently paid 20usd to ship a pair of running shoes with the box from taobao via superbuy to Norway.
