Still hunting for that perfect festive party dress? We know shopping for presents and planning for all those Christmas festivities can mean a limited budget, which where the secret weapon of supermarket shopping comes in. Party frocks are the ultimate in throaway fashion so it often makes sense not to spend a fortune on one, which is why two of these come in at under £20. The other is a new version of the Gok Wan for Tu Ultimate Wrap Dress we reviewed back in October - a great investment piece that is the epitome of the phrase 'fit and flatter'! It's £40, but it's more than just a party dress. Wear it for your office do with some sparkly jewellery, then dress it down with boots and tights for the rest of the year!
