This is a great formal look that couples a silk Kay Unger black and white bustier with a silk Tadashi skirt. The bustier is a size 6 but the Kay Unger brand runs small and the Tadashi skirt is a size 4 and that brand runs large. Check the measurements but if you are a size 4, this would be quite an elegant look for a very reasonable price! http://www.ebay.com/itm/Kay-Unger-Silk-Bustier-Black-and-White-Floral-Design-Size-6-/172613067414; http://www.ebay.com/itm/Tadashi-Long-Black-Silk-Mesh-Skirt-With-Satin-Bands-At-Hem-Size-4-/172606220683
