The Duchess of Edinburgh expertly combined quiet luxury with workwear chic on Thursday as she stepped out to open The Edinburgh Building at the David Lewis Centre's site in Warford for those with complex needs including epilepsy, learning disabilities and autism.
Duchess Sophie, 59, was spotted wearing a lovely chocolate brown blazer from Gabriela Hearst. The single-breasted 'Stephanie' blazer was teamed with a pair of wide-leg grey trousers.
For touches of luxury, Prince Edward's wife wore a chocolate brown pashmina over her shoulders to look like a 1950s movie star and popped on a pair of pointed-toe stilettos. She also wore a fitted brown shirt.
The royal rounded off her look with a clutch bag in the same autumn-appropriate hue and wore her sandy blonde hair in a voluminous updo. "We were delighted to welcome the Duchess back to David Lewis in our 120th year!," the charity penned on Instagram.

The royal added another autumnal hue in the form of her patent burgundy heels - the 'Ixia 80' style from Jimmy Choo. Sophie also added a zebra print bag from Sophie Habsburg.
