Honestly, I've had it for a few years and never wear it. Red isn't my color and I keep putting it on and then taking it right back off. It has removable pads, is basically brand new and comes from a smoke-free, pet-friendly home. I can't tell you for sure what the actual size is. I'm a 36 B (that runs on the smaller end of B) and it fits me. Could mean that's a small or a medium, but I don't know what the specific sizing for this bra was.
