The maxi dress I have is 153 157, sorry can't do a link. I have the purple option ( out of stock at the moment ) and the blue option. What is odd is that the purple one is a slightly heavier fabric which feels and looks more like viscose, and the blue one that I bought more recently is more like the normal polyester jersey, both fit exactly the same. I am a size 8/10 on the High Street and usually order an XS in Antthony's range. The prices have risen quite a lot since I ordered mine a few months back.
