Trendabl
The latest startup to embrace the power of celebrity influence is an iPhone app called Trendabl. Billed as “Instagram for fashion,” users can share photos of outfits and tag them according to label, price, where it’s from, etc. You can also comment on and like things. They launched this week with an impressive roster of celebrity trendsetters including Mary Kate and Ashley Olsen, Harley Viera Newton, Whitney Port and Brad Goreski and plan to eventually expand into ecommerce.
