I would personally never buy from Milanoo, I've heard too much about it and the few posts here have been the first positives. I's rather not risk my money (should I have to ship it back and fork out more money to get the right item) or the stress and disappointment.
I don't generally buy my costumes unless I'm strapped for time with Uni and making sure I have time for my other half and making sure he has the costumes he wants. But I did buy a Serah Farron costume from CocosilverHK
She makes beautiful costumes which came to me just as displayed in the image - I was the first buyer for this particular costume so I was a bit sceptical, but a lot of Serah costumes lack the holes at the back.
My costume was of a standard size and fitted fine, however the skirt was very short so I would probably recommend you request it lengthened depending on what costume you buy
