Nobody's Child Women's Polka Dot Halter Neck Midaxi Slip Dress - 6 - Blue Mix - Available at M&S

With its crisp polka dot print, this slip dress from Nobody's Child is a striking choice. It's cut in a fitted silhouette for a figure-defining look, with a flattering v-neckline. A halter neck adds flirty detail to the sleeveless bodice, while a fluttery tie at the centre front creates pretty movement. The hemline falls to an elegant midaxi length.
