A new arrival today - and with splendid timing it's topical too. No sooner does Woman's Own publish its Blast That Bra Bulge Diet ("Your back is one of the first places you lose fat and we'll show you how") than along comes a lingerie innovation that makes it redundant. The aptly-named Bra-lellujah! from shapewear expert Spanx is specially designed to do for your back what the famous Power Panties do for your lower body: give a smooth silhouette where once there were bulges. Available now, £47.
