Corsets are a type of clothing which are typically worn to support and shape the waist and torso. While this makes sense for soft-bellied mammals, the benefits to other classes are hard to figure
Birds, in particular, have very rigid bodies; their ribcage encompasses their entire torso to the hips, and the ribs connect together firmly
This seems like it would make corsets rather redundant for avian beings. While corsets could perform other functions besides shaping, these also seem plausibly achievable without a corset, especially on the hard avian body
Would avian beings actually benefit from wearing corsets? Or would they simply not need to bother?
