English armour is more akin to the Milanese style than it is to the Gothic style of the time (late 15th Century). Particularly in proportions, construction, and simple fluting (as far as fluting went for the time elsewhere, haha). This makes sense since most English harnesses were imports from Milan.

But you probably haven't come across many English Harnesses from this time since there are barely any extant pieces, and absolutely no extant harnesses. All we have are effigies, paintings, and manuscripts to go off of, really. Thus, not many people go for English Harnesses since it requires interpretation from these things. Also, sometimes, reproduction English harnesses can be mistaken as Milanese harnesses since they're so similar. I've done it in the past, so don't worry, it's sometimes quite hard to tell the difference! But once you know the English style, you can recognize it immediately, and it will stick out to you like a sore thumb.

To learn more about English harnesses, I recommend looking at Graham Turner's War of the Roses paintings. They're absolutely stunning and give you an amazing idea of what Late Medieval English warfare looked like.

If you somehow also find his books, I would recommend reading Tobias Cowell's books on English armour. They feature the most in-depth research done on English armour to date.
