Susannah at CargoCultCraft spent a year on her Fashion on the Ration project, buying and making clothes within the constraints that British families faced in 1941. She's collected both the original government restrictions and information on how home seamstresses managed, from paring down patterns to take up less fabric to remaking worn-out men's clothes into women's. This is one of those things that I was terribly curious about and elated to find out that someone else had already done the research (literally!)!
Shelley at New Vintage Lady makes vintage garments with a focus on drafting or altering plus-size patterns! Her blog has lots of tutorials, and the 'foundation garments' and 'sleepwear' sections of her website contain some very useful information on making these overlooked items (not to mention her blog, which is a veritable wealth of inspiration for the "stout" figure).
