Dressmaking

I saw some material whilst on holiday and decided to buy enough material to make a dress and jacket. It is still in the bag, I can't find any of my old patterns, it has been 20 years since I made the last one, cannot find a pattern or a dress I can copy one from. Has anyone any suggestions for a dimple sheath dress, midi length, and waterfall jacket. Thanks in anticipation. If not it could end up covering the garden chairs, it is a very bright design.
