I'm not a fashion expert and I really don't care much for it but this was the most horrible dress I have ever seen. Even on a coathangar bodytype like VB herself it wouldn't look good but on an average body it's just hideous. That's 850 £ unwisely spent. She could and should have gotten a dress from M&S for 50£ and actually looked good.
