I'm fed up of wearing shapeless tops and dresses. I often wear leggings with long tunics or jersey dresses with thick tights, but would like to clinch them in at the waist. However ... I'm a size 16 at present (working on losing weight though) and I'm not sure what would suit me ... I don't have any belts! 
Can anyone suggest what they would wear in my situation and if possible link to them? Thanks.
