A black x white Angelic Pretty OP. Can't find a listing for it but from the tag I believe it's quite old. 
I am the third owner. The dress has a general feeling of wear and the lace has yellowed slightly. 
The dress has full back shirring so can fit up to at least 95 cm bust, 75 cm waist but can probably stretch a bit further still. I don't have any official measurements.
