TIE THE KNOT: Tying the knot has never been so easy, thanks to Hermès International’s digital styling helper. Practical as much as it is fun, the Hermès Silk Knot phone app provides users with whimsical yet chic ideas to tie the French brand’s silk scarves. Step-by-step videos and pictures teach how to master six different knots, to which a series of new knots will be added each season. Users are invited to take pictures of their personal style and post them on Instagram, the most original of which might end up on updated versions of the application. The app is available for free download from the iTunes App Store.
