Such a pretty piece that sadly does not fit me, alas I tried to remove shirring in the back as pictured, but there is still shirring at the top of the back panel and in the waist so there is no change to the shape. It is missing the back corset lacing (missing when I purchased but can be replaced with another grosgrain/petersham ribbon in the same color as the front corset lacing.) This piece also has boning in the front only, a side zip, detachable waist ties, and is made out of beautiful cotton with a lined skirt.  
Bust: 84-92cm
Waist: 68-74 cm
Length: 92 cm
I do live with cats but they are not allowed in my room, full disclosure for those with severe allergies.
I will also be including cute woodland animal socks that somewhat match the dress, for free.
