I met Lesley Eccles (co-founder of FanDuel.com) from Scotland, and she was wearing the most divine red mary-jane heels, which I believe she said were from Revel (a UK brand). Not being able to find them online for purchase, I found some similar alternatives:
Sofft Corine in Red Hot/Red, $99.95 from Zappos.com
BP. Maddie Pump in Red Patent, $59.95 from Nordstrom.com
And if you want a brighter red…
Franco Sarto Essence in Red Suede, $88.95 from ShoeBuy.com
Demonia Vanity in Red Patent, $39.95 from ShoeBuy.com
