The Green Lantern beauty has teamed up with bosses at luxury goods firm Sandast for the James Bag, a custom cognac-coloured creation made from premium leather, with a plaid lining.

The item is available for purchase from Lively's lifestyle website, Preserve, but the accessory doesn't come cheap - the bag is priced at $860 (£538).

It's not the actress' first foray into fashion design - she recently unveiled a capsule collection of clothes she co-created with experts at eco-conscious brand Amour Vert specially for Preserve customers.

Lively welcomed her first child with husband Ryan Reynolds in December (14).
