I just bought a pair (two actually) of the cuttest high heels in the world (at least I think so). Unlike the picture, mine are in a chocolate brown and jet black. They also have a t-strap. If you are interested in a pair, you cn find them up to a size 10 at Cutesy Girl . These heels will work great under a pair of wideleg trousers.
The heels are really sturdy, and they do not seem to pinch anywhere.
