From her now-iconic blue Issa dress to a Burberry trench coat that sold out in hours, the world is paying close attention to the future princess and her style picks.
But you don't have to have a royal budget to copy her looks.
Blue Engagement Dress
The blue Issa dress cost more than $600. It had sold out 24 hours after Middleton wore it to her engagement announcement at St. James's Palace in London.
For Less: Get this look-alike dress from Max Studio for $29.99 at Marshalls.
Pair it with black pumps from Forever 21 for $19.80 and a ring from R.J. Graziano for HSN.com at $29.99
This look has some of Middleton's favorites: a tweed jacket, a structured beret and knee-high suede boots.
Engagement bauble, $22, from Kohl's.
The Red Suit
Middleton was seen wearing the Luisa Spagnoli suit, which costs about $800, for an appearance at St. Andrew's University.
Burberry Trench Coat
Middleton was spotted wearing it a few weeks ago in Belfast and it sold out hours afterward. Hers sells for about $1,000.
For Less: Topshop khaki trench, $180. It cinches at the waist and echoes the same skirt detailing as Middleton's original, making it very feminine and very polished. It's a shade or so darker than her coat but more realistic for a non-royal because it doesn't show all the daily wear and tear as easily as a lighter shade would, Bergamotto said. This ring in this look is from QVC and costs $39.54.
