I've spoken about Little Black Dresses so many times in recent weeks that even I'm bored of them (and at last count, I had about 20 of them in my wardrobe). Still, there's no denying the LBD is the perfect wardrobe staple for this time of year. The right accessories, hair and makeup can dress it up or down for any festive occasion. So, with that in mind the first gallery as part of the 100 Cheap Party Dresses list is devoted to LBDs - strapless, pretty, prom style ones to be exact. And all these babies are between £20 and £45.
