Have a true to size indicator, for all sizes available have a model or staff member rate the fit honestly, ie size 14 runs very small order up a size. I have ordered a few dresses that are sized 14, however they are more an AUS 10-12 which is demoralising. I honestly bypass these brands as no woman wants to have to go up a size or two. The models are beautiful but being so slender this often isn’t obvious when looking online, will lower return rate and have happier customers.
