The Ametora's fabric is relatively thin with a slight sheen, whereas my Vintage Ivy oxfords are thicker, softer and have a more matte texture. I've only washed the Ametora twice so the attributes may change over time. The thin fabric can make the collar feel quite floppy.
Interestingly, the buttons on the Ametora are spaced further apart (10cm instead of 8.5cm) which makes it easier to tuck in depending on your trousers. The MOP buttons are noticeably nicer in colour, texture and shape than the ones on my Vintage Ivy shirts.
I have a 40" chest, 30" waist and wear the size 15. Surprisingly easy to style with high waisted trousers if you can get the proportions to work.
The vintage ivy oxford is not the thickest to begin with. Does this mean Ametora is more like pinpoint oxford? I notice usually with these supposedly "luxurious" cottons they tend to give us less of it!
The farther apart button spacing is the intended feature, which matches that of old Brooks Brothers shirts from the 60s, 70s, and 80s (I just confirmed this measurement). And presumably the Mercer and Sons shirts, which I don't own
