The site has now launched and the official description is below;
Boutiques.com is a personalized shopping experience, brought to you by Google, that lets you find and discover fashion goods through a collection of boutiques curated by taste-makers — celebrities, stylists, designers, and fashion bloggers. Boutiques uses visual technology to help fashionistas discover and shop their look and creates the opportunity for designers to showcase their collections and latest inspirations online.
It is only currently available in the US but there are plans to roll it out to other countries. Have a play and let us know what you think.
