There are a huge variety of original nineteenth century corset in the world, which show us how the manufacturing became increasingly elaborate decade after decade. Also sewn in cloth of linen or heavy cotton, they were densely stitched from top to bottom and reinforced by lots of whalebone. Often the ribs were so close to give a rigidity that called to mind the heavy iron corset of the sixteenth century. This explains why their manufacture remained a male privilege, which leads us to believe that the test in the dressing room could embarrass, or were pervaded by a subtle malice. Most of the differences between a corset and another was due more to differences "by hand" than by "style". Instead, other differences between a corset and another could be determined by the lady age or corpulence, as well as by the geographic location. So it is difficult to define a model of corset as typical of that decade, while in the next century will be easier to mark the differences in fashion.
