Lovelyshoes.net is a Chinese-based online store that wholesales shoes and bags, and I've reviewed stuff from there before on my blog. The shoes are really cheap (like $10-$30) so it's great for people on a budget! However it's copped its fair share of bad reviews on the internet for the quality and customer service. My personal experience hasn't been as bad as others though, and although there are some 'misses' in this haul I still think they were kind of expected for the price I paid.
I got 4 pairs of shoes (the black ones with the metallic heel are from MissGuided) for about $51 plus shipping of about $49 (yes, it's almost the same price as the shoes themselves!) = $100.
Shipping to Australia took about 2 weeks.
As for sizing, I always order Euro size 37 from Chinese wholesale websites which seems to be pretty consistent and fit me perfectly.
