So after looking at the posted pictures from other people, SkyCostume may not be the same as Cosplayskye but I can't be sure. My suit is definitely different from Harrypotterfan's but it looks a lot like snakeeye316's.
Instead of Snaps, mine is velcro and the detachable collar has the leather harness attached to it. I'm currently traveling so I don't have pictures to explain, but with the harness sewn into a loop on the collar, it almost lets you wear the collar piece like a backpack.
I ordered it from Skycostume on eBay and just did the premade size "Large", so no custom sizing for me. The Jacket does come out to be just right on me, surprisingly, and that picture would have looked better if I shifted the belt down a little to hide the edge of the jacket. I'm a 42" chest and a shade below 5'11" tall so it just happened to work out right and coincided with their sizing chart. Now when I ordered it from ebay, it came a couple days late, and when I asked, they responded that because it was a new costume they were working some things out with it. That may explain the changes from Harrypotterfan's suit to mine and how mine is more similar to snakeeyes' suit.
As far as the suit fit goes, it fits well, but I guess it looks a little big because the arms are a but long. I'm not so worried about the pant legs since they'll be tucked into boots anyway. Again, still very happy with the suit.
