If anyone knows a thing or two about dressing up, it's Kate Middleton. The Princess of Wales has been attending royal engagements for close to two decades, and even her more casual outfits are chic and put together. Of course, with so many events on the calendar, the 44-year-old has learned a handful of valuable fashion tricks - including opting for footwear that looks fancy, but is secretly so comfortable. On more than one occasion, Middleton has stepped out wearing Aldo's Nicholes Pumps - a $54, budget-friendly style that, shockingly, is still available on Amazon.
