IRCC 3: Burgundy and Silver Huge Sleeved Frock

So I have decided to enter the The Third Annual Italian Renaissance Costuming Challenge hosted by The Realm of Venus, and in true 'me' style have probably bitten off a whole lot more than I can handle in choosing this dress.  I figure, if I'm going to make a big frock I might as well make A BIG FROCK. 

Although I dearly love the orange and green velvet combo, I need to show restraint and use fabric from my stash.  I have 3 m of silver and 3 m of burgundy duponi silk, both from $5/m clearance sales and I'm hoping that will be enough to make this gown.  I'm going to make the sleeves a little less pouffy I think and the skirt will most likely be less full.  I've decided to use my Frankenstein pattern with side back and front lacing so that when/if I lose some weight I can still wear this gown.  I've drawn up a sketch of how the piecing will happen, I think the best way is to make a calico muslin and then cut up the pattern pieces from that.  I will definitely need to keep my wits about me with this one!

You can see my very dodgy sketching, this is mainly for the layout of the piecing, I think this will need to be fully lined, not in fur like in the portrait phew!!
