Betony Vernon, who you may recall collaborated with Alexander Wang on a collection of “Second Skin” bracelets, is about to release a book titled Boudoir Bible, just in time for Valentine’s Day.

An uninhibited guide to sexuality, Vernon illustrates her expertise in sexuality and sensuality in a short film titled Evanescence, co-directed alongside Frédéric Sofiyana. The short film will be released on the same day as the book. Enjoy the teaser video above as a precursor of what is to come.

Straight from the Autumn/Winter 2011 runway, the “Second Skin” and ”The Offering” sterling silver bracelets designed in collaboration with Betony Vernon are now available to purchase on Wang’s etail site. Priced from $2,500-$3,000, there are just eight pieces in total and each is numbered. On the next page, see the bracelet as worn on the runway. If you will look, you’ll see that it’s not exactly a bracelet as much as a hand cuff. Or something.
