Earlier in the Cheap Party dresses rundown, I featured a whole gallery of strapless black numbers. But you can never have too many LBDs in my opinion, so here are two more that definitely make the grade (especially now their prices have been slashed in the sale). They're both from New Look, and start at £20 for the velvet spot dress (very Luella) with the frilly, ruffled prom dress coming in at £35, which is a great deal considering all the detail. Move fast as sizes are already limited. That's what happens with bargains like this!
