Embellished fishtail dress £95 at Miss Selfridge >>>

Miss Selfridge's line of pretty party dresses this season is the best I've seen from the brand for years. This long-sleeved, fishtail midi dress is so different to the usual bodycon minis and one-shoulder satin numbers that we see around the festive season, and as a result it's so much more showstopping.

The joy with this is despite being very covered up, it still looks quite sexy due to the sheer fabric, the pale colour and the embellishment. I'm not sure about the swirls around the bust - I fear on a bigger bust would this look like a bullseye! But if you're tall enough and slinky enough to pull off long sleeves and a midi length, this is a very dramatic way to do so!
