Catherine carried LK Bennett Delilah suede clutch at the wedding of Harry Aubrey-Fletcher and Louise Stourton in January 2011. It seems the clutch is from her pre-wedding wardrobe as at that time it was already sold out. Thanks to the WhatKateWore for the information. The aubergine clutch crafted from suede material has a flap closure and a pretty bow on its flap.
