Purchasing the right size was hard. I usually go by what the model wears which was confusing as the model for this product is a 36 with no reference to what she regularly is in AUS sizing and no AUS conversion chart- This would have been extremely helpful. I had to return my first pair and reordered a size 28 after talking to the online chat to work out my correct size. Returning the product was free, simple and quick. I have already received my refund- thank you adidas. The post bag it arrived in wasn't reusable with no option to reseal and send back like other shops. I wasn't able to repurchase my pants for the same price I originally paid as that sale had ended which is slightly annoying. Lucky the pants are cute. I'm 42, 3 kids, strong build and these pants now fit like a glove. I'm also 5"3- they will be taken up before I head out in public.
