Modcloth's Woven for the Weekend straw clutch is pretty much the same shape and feel of the Anya Hindmarch Fan Clutch (seen below) than Kate wore on Canada Day, including the tassel.
While we would love the copy to have some of the colour of the original at $27.99 its a bargainsta's dream. And while the original featured more crochet (the Duchess does seem to love her some kneedle work) and beading we think this woven option is still a great alternative.
One of the comments on the Modcloth site does warn that "the woven parts are much thicker and not as tight as depicted...also...not as white as pictured and more light brown. Still a cute clutch..." So keep that in mind if you're planning on ordering.
