Vintage Little Mistress of London Fitted Party Dress

I picked this cutie up on a recent trip to New Zealand, it's such a perfect fitting dress!
From Office to Cocktails, this dress will take you there!
With a higher fitted waistline, this zip-up-the-back dress features padded half sleeves.
Marked a size 6, it measures 18" armpit to armpit, 28" around the belted waist, 38" hips and 33" long.
By Little Mistress of London, it feels like a polyester, I am assuming it's washable.
Perfect no iron and easy to wear!
