I splashed out on a new bag (instagramed here). I love that it's a modern take on an old calssic. The leather is matte and the hardware is tarnished so it gives what can be quite a preppy style a bit of edge. I like dressing it down with cut offs and flats but it will work great for cocktails too.... I am totally justifying a very expensive purchase!
