I don't know why the title says "steel boned" because steel it is clearly not.  The boning is PLASTIC like the item description says.  If you're looking for this to cinch or support anything, look elsewhere.  The bones are cheap and flimsy and bend easily.  The fabric's not much better, a flimsy fake leather that's pretty similar to a vinyl tablecloth.  The listing is also incorrect in saying it comes with black lace, mine came with red.

The MAJOR problem I have with it, however, has nothing to do with the poor fabric or boning.  I'm a size 12 and an E cup so I  ordered  the XL, in correspondence with the size chart.  Once it arrived I realized there was a HUGE issue, I couldn't even start to get it on!  The bottom of the corset, fully unlaced I could just barely get closed, bu the top I could not even bring anywhere near closed.  The closure only reached about halfway below my beasts, leaving about a five inch gap from closing.  Once I took it off and looked at it I quickly noticed the problem!  The open cup spaces measured about 2.5 inches across each!  (Not an exaggeration; I measured them!)  Exactly how a woman who wears a D/E cup is supposed to fit into a space 2.5 inches wide I would really like to know!!!  It seems the corset may have been sized up but the cups were NOT!  And on top of that, the corset cannot be returned for "hygiene reasons."  So it was completely unwearable and unreturnable.

If you wear anything but an A-cup I would advise against buying this!!!!
