I've never bought a real corset before, mostly because of how expensive they are.  I wanted this for a halloween costume I'm putting together this year, so I took the plunge.

It came in a nice zipper bag that I can re-use, which is cool.  I don't recall if it listed the removable garter straps, but it had those too.  The lacing instructions could have been clearer, but common sense works quite well to fill in the gaps.  The sizing chart was right on.  It just barely tightened enough to meet with the modesty panel in the back on the first wearing without too much pulling - so there's room for pulling tighter and for the material to stretch like it's supposed to.  I was surprised how stiff the boning was, but I'm pretty sure that's what makes the difference between the cheapy corsets and the real ones!
