I bought the boots worn in yesterday's outfit back when I was determined to own a pair of heeled harness ankle boots.
This obsession was due to reading Fashiontoast and loving the outfits she paired with a pair of Jeffrey Campbell boots. She was able to pair them with a fancy dress or casual shorts and it always looked awesome.
Jeffrey Campbell rumi boot is available here. In addition, I put together this set via Polyvore showcasing other heeled harness ankle boots.
