Trust me, these boots look lovely with evening wear ;)
I finally did a search online for wide calf boots and guess what I found? A company specializing in wide calf boots! http://www.widewidths.com/ has all sorts of boots in wide calf, extra wide calf and super wide calf and I found a pair I thought looked great. I measured as instructed by the website and ordered them. A week and a half later the boots appeared on my doorstep thanks to door-to-door delivery! I was a little nervous at first, but they actually zipped up.... all the way up! [Cue the angels singing and the Hallelujah chorus]
This is the boot I purchased. I thought it had a classic look and shouldn't go out of style. It is the Ros Hommerson Ella boot in super wide calf.
