Heavy Red boned corset, size small. Tried on but never actually worn.

Heavy Red boned corset, size small. I would say this is a firm size 2. I’m a size 2 & could get it on, but my boobs were up to my chin & I could barely breath let alone sit down. This was probably due to having a larger bust & the item having zero give. I love this corset but I would need to reorder a medium next time
