Looking under Ozbargain Wiki, there are bargain different categories but does not seem to have fashion.
One of my girl friends suggests ozsale.com.au. OMG, have a look at the review. My eyeballs nearly pop out. Only 1.7 of 5 stars.
Where to hunt for bargain fashion? Cheap but not cheap.
Asos when they have further 20% off every few months.
