Bydee Ebony Corset in Onyx Size Medium

I love this top but it sadly doesn’t fit me. I’ve worn it once, but there is some wear (which shouldn’t impact the fit)—the zipper pull is missing and there was a piece of plastic boning in the front center that has been pulled out. If you are unfamiliar with this brand, it is Australian sizing, so the fit is quite tight. I’m a 6, 34D, and this is too small for me.
