Very gorgeous OP dress in Lavender from Angelic Pretty. I adore it, and it's really flattering, but I prefer the JSK version. I think I'm its third owner, but it has been kept in very good condition. I've worn it very few times, and I can't see any flaws.
Lolibrary measurements:

• Bust: about 90cms, no shirring (I've got 93cms and it fits me perfectly!)
• Length: 89cm + 3cm lace
• Waist: about 76.5cm
• Cuff: about 26.5cm
