I am looking at a couple of Anthropologie items to order online. Returns will be tricky from NZ.

I am a size 12 in NZ mostly, occasionally a 14 which is either a Medium or Large here. This equates to an 8 in the US from most size charts and when in the US last year most of my pieces I bought were US Medium.

When I look at the size chart for Anthropologie I seem to be larger than an 8....does Anthropologie fit small/am I delusional on my size?
The only Anthropologie item I own is a Bailey 44 dress, size Medium. It is body con, but seems the right size as they are supposed to be fitting (I think?)

I know years and years ago the US was only one size down (I was a NZ 12 and a US10) but I thought that US had more "vanity sizing" now.
