We know The Saturdays love a good barg or two, but Rochelle Wiseman aka the new Mrs Marvin Humes has proved she's the thriftiest of all the ladies in her £12 Fashion Union dress she wore out and about in LA yesterday. What with Halloween coming up, the cute skull prints make this the perfect investment piece to see you through October.You might need to add some tights and a jacket though as we're not all fortunate enough to live in the LA sunshine, are we Rochelle?
