I made England's uniform myself. I found a blouse pattern that was pretty close to the jacket. I just modified it by adding extra pockets. For the pants I used a pattern for pyjama bottoms for the pants which made the costume more comfortable and easy to tuck in my boots.
Also, I suggest breaking the boots in before wearing them at a con. I didn't and by the time the weekend was over my feet were killing me!
I did find Romano wigs on Ebay, if you need that. My friend cosplayed Canada and we had a hard time making the curl, but one of the wigs on Ebay had Romano's curl attached.
