Corsets are undergarments with a variety of usages, including supporting large dress and such. While this is functional for birds and lizards, I feel there is another type of being to consider, that being humanoid frogs
Unlike birds and lizards, which have complete ribcages that encompass the whole torso, frogs have no ribcage at all. In particular, the humanoid frogs in my world have narrow spines, not much wider than that of a human, with shoulder blades and a humanoid pelvis without any ribs, sternum or collarbones. Their torso is otherwise humanoid in shape
Given this, would a full corset aid these frogs with supporting heavy dresses, or would their minimal skeleton make corsets do more harm than good to them?
