As Jillian correctly pointed out, a bit of red sole was visible in the shoe picture in this post. The red sole is the "signature" of one of the hottest names in the shoe industry, French designer Christian Louboutin. The shoes are $595 and are available at Barney's online. (Ha! Now the shoe is on the home page!)
But cute mary jane pumps can be had at far less exorbitant prices. Here are a couple of prime choices:
On the left is BCBGirls' Titta pump, available also in red patent. It retails for $97.95.
On the right is Kenzie's Cobb pump. The above is actually patent, though the small image doesn't give that impression. It is also available in black patent with black leather piping, but this version isn't nearly as attractive as either the grey or the BCBGirls black with white trim. It retails for $80 at Piperlime, the fledgling shoe shop Gap started this past fall. I can't say I'm a big fan of Piperlime -- they have some nice shoes and some nice search features, but their brand selection isn't that great.
