Queen Letizia shows off very toned arms in fluffy corset-style top as she attends concert

Queen Letizia, 47, looked sensational in the outfit, which made the most of her slim frame. The mum-of-two chose a dusky pink strapless top, £587, from The 2nd Skin Co. which was modified for her with feathers. Shoppers can buy it online, but the available option has ruffles instead. The trousers she chose are also from The 2nd Skin Co. and cost £475.

A long ribbon belt with a diamante buckle added further drama to the look.

Letizia kept everything else simple, opting for a simple black satin clutch from Magrit and black leather court shoes, also from the brand.

A pair of black sparkling drop earrings from De Grisogono and a simple gold ring completed the look.

Amping things up with her makeup, Letizia chose shimmering copper eyeshadow and extra long lashes.

A sweep of peachy bronzer and a brick red lipgloss topped things off.

The royal has not spoken out about how she stays in such great shape, it is thought she follows the Perricone diet to help her maintain her slender figure.
