This is a beautiful silver gray brocade, under bust, boned corset.
It has 5 metal "locks" down the front.

Corset laces in the back, and allows for appx. 2" extra width.
These corsets run about 2 sizes smaller than what is labeled on the package, so we have down sized them in this listing, based on modern U.S. woman's apparel guidelines.

The following sizes are measured waist sizes in inches, with the corset laying flat, and laced closed with the 2 sides together. There is a fabric panel underneath the lacing that will allow about 2" more without seeing the garment underneath.
(As you can see in picture #3 & 4, I had used the XS one, and it was too small for the dress form.)

XSmall-24"-26"
SM-26"-28"
MD-30"-32"
Large-32"-34"
Xlarge-34"-36"

Item listed is for the corset only. 

This design, makes a great Steampunk  or Pirate accessory.
