There are two rows of boning sewn inside in the back of the bodice.
This is over 100 years old, so it does have minor wear, fraying, but overall I'd say this is in remarkable condition for its age! This would be perfect for a gothic modeling shoot or to add to your Victorian collection.
You should have a 32-33" bust and 22-24" waist to wear this. (I was unable to button it all the way on my mannequin in the rib area.)
