The hat I got from Hatcrafters
http://www.hatcrafters.com/page6.htm I got #64, the puritan and simply asked them to do it in black with a regular 1 1/2" hatband and a flat brim. Came out pretty much perfect. They make them to fit your head. Be sure to measure it with the mask and the wig on. The prices are extremely good for custom. Like $69.00 I think I paid (don't quote me on that).
Here's the same image above in its full size

You can see the belt laid out flat which will pretty much give you a pattern. The buckle I sculpted and cast in pewter (not that hard actually, I think I have a couple casts left, but they're 700 miles away in storage sadly), but I scaled it at 2 1/2" where the belt goes through. The front where the buckle is is non-functional as you can see in the pic and it hooks in the back. The screen-used is like this as well. The belt itself I made from 6 oz leather. I used 1/2" strips of aluminum that I bent to shape for the dagger holders and put in place. Then I backed the whole thing with piece of soft chap hide and edgestitched the whole thing together.
The mask I got from Sgt Fang here on the RPF and painted it myself. Also took a little reshaping.
I think the doublet is pretty easy to modify a pattern for. Its a pretty simple mod to a cavalier doublet. The trick is knowing the basics of doublet construction. That's what gives it its shape. Basically, instead of lining it with a soft, satiny fabric like most garments, doublets are lined with medium weight canvas, twill, or linen, backed with cotton batting and quilted. This creates a stiffer body. The doublet nearly stands up on its own.
The hardest part about the doublet is finding a good fabric for it.
The pants are actually Dickies and the Gloves are cut down riding gloves (his are a bit shorter than normal gauntlet style gloves).
Hope this helps.
