I know, wedges aren't usually my thing, but I think these are seriously gorgeous. What a fun way to have black shoes: sparkly! and with a wine-red heel and ankle strap.
Typically, Jeffrey Campbell wedges verge into the 'completely ridiculous' category, but I find these rather elegant and versatile. Are they maybe a little too 'winter' for year-round wearing? I think they'd be perfect for clomping around London all day.
If they're your cup of... wine(?), you can buy them from Modcloth for $143.
