Sewing for Halloween!

So, my dad got these bright red shiny Nike shoes [source], and decided he wanted a Dorothy dress from Wizard of Oz to go with them for Halloween. I found Simplicity Plus Size Pattern 4136.

Unfortunately, this pattern isn't going to come anywhere close to fitting him, as 1) his measurements are way off the charts, and 2) he's a dude, with a big ol belly. I had "extended" measurements before, so I figured I could probably do it again, but the man belly caused a new sort of problem, since the pattern is shaped for roughly hourglass shaped ladies. I had heard of a "Full Bust Adjustment," so I tried googling "Full Belly Adjustment." Lo and behold, I am not the first one to try to alter a pattern in this manner, unfortunately each source does it differently, so I will need to experiment.

Other bonus to me actually digging out my sewing machine & accessories, I found a BOX of PATTERNS! I had totally forgot about my collecting random patterns I've found at thrift stores over the ages, and most of them were costumes, too! Unfortunately I either wasn't paying attention to the sizes or didn't realize pattern sizing is totally different than consumer retail sizing, so even though I'm pretty slim (36b-30w-41h), there ain't no way most of those will fit me without modifications, either.
