This isn't any old dress this is a Karen Gillam creation you'll absolutely 'Love to be petite in'.
You are guaranteed to have a great evening in this truly designer petite dress. Why? Because the red net at the hem means that you can pop on your red shoes (without ankle straps!) and step out in style. Provided you wear a flash of red near your face, be it a brooch, fascinator, necklace, earrings etc., it will draw the eye from top to toe giving the illusion of height.
The dark lining and gathering of the lace from the waist diverging over the hips will slim the tummy and emphasise your feminine curves. Wear the lace sleeves on the shoulders, if you prefer, or off the shoulders, as here, to reveal the dresses shoulder straps. 
Don't worry about the length of this fabulous dress, it will look just as good worn ballet length as it will ankle length depending on your height.
