I love a fashion obsession, especially when the obsession is with a shoe. Today I came across one of the most specialised blogs dedicated to footwear, and not just any old footwear, the creme de la creme that is Louboutin. Pigalle Passions Blog pays homage to the classic and elegant Pigalle Shoe that has taken the fashion world by storm, its been seen on pretty much every celeb going over the past 6-12 months from the red carpet to off-duty looks. I personally love this shoe and no styling job is complete without calling in at least 2 pairs for an assignment. Check out the full list of celeb stalker sightings at their blog www.cl-pigalle.blogspot.co.uk. Below: Katy Perry, Fergie, Hedi Klum, Kim Kardashian, Kate Moss, Gemma Arterton.
