Pin Up Couture flat shoe sizing runs standard to US sizing. This is the same as Australian sizing: if you're a 10 Australian women's, you will be a 10 US women's.
Pin Up Couture women's heels tend to run small so we advise sizing up for these. E.g. if you're a 10 in Australian shoes, you would best suit an 11 women's heel.
For half sizes or those between two sizes, we recommend sizing up. Eg: if you are a 9 Australian women's, and you sometimes fit into an Australian women's 8, then we suggest getting a size 9 US. But if you are a large Australian 9 and you sometimes fit into size 10, then we suggest getting a size 10 US.
