Spanish Fashion Victim

Because I leave for Pennsic in less than 5 days, I've decided I need a new dress.  Obviously.  :)  To be specific, I need an obnoxious parti-colored bias cut plaid dress, such as were popular for about 20 minutes in late 14th century Spain.  Leave it to the Spanish to come up with the craziest of fashion trends.

Anyway, I have the gown out and about half way put together, I'm doing this by machine partly because I have only a few days but mostly because the fabric is mainly cotton.  It was either that or heavy wool coating and I'm not about to wear heavy plaid wool in the middle of July in Pennsylvania.  The plaid is cotton and the solid kermit green is a cotton linen blend, since that is what they had at the fabric store in a decent selection of colors.  The colors remind me of Kermit and Miss. Piggy for some reason, I'm quite pleased with them even if the whole thing leans a bit towards the obnoxious (isn't that the point though?)

What I am trying to decide at the moment is how to close the front.  Based on the picture, it sort of looks like the gown is probably laced up either in front or down the sides and there does not seem to be a visible undergown.  It's a little hard to tell and I have not been able to find a higher res version of this image to see if there is any more detail.  Because the fabric is not so very sturdy I will be wearing a supportive layer underneath, I'm wondering how I ought to close this thing up.  I'm leaning towards buttons even though I really can't find any suggestion that this is how this sort of gown would have been closed that way.  It would certainly be easier for my purposes.  A laced overgown over a laced undergown sounds like a big PITA.
