CaptionKate Middleton London - Arabstoday The Duchess of Cambridge Kate Middleton wore a lace dress from Zara while attending Take That’s Gary Barlow perform at the Royal Albert Hall. The hemline on the £69.99 high street dress was significantly higher than anything the 29-year-old has worn for a public engagement before. While it showed off her shapely legs, it also appeared to make her slightly self-conscious, and she could be seen repeatedly tugging the dress down. However, she added a touch of her characteristic conservative style with opaque black tights and matching heels, and completed her outfit with the classic black Ralph Lauren jacket.
