Kate Middleton is radiant in powder blue Emilia Wickstead on visit to Luxembourg

The Duchess of Cambridgejust hit another style home run.

Kate carried out her second solo overseas trip today, visiting Luxembourg to commemorate the 150th anniversary of the signing of the Treaty of London with a series of engagements.

The Duchess chose a few favorites for today -- her favorite color, blue, and one of her favorite designers, Emilia Wickstead. She also turned to her jewelry go-to, Kiki McDonough, for a pair of sparkling blue topaz and diamond drop earrings. The dress is bespoke, and the earrings retail for a cool £3,500 (around $4,508).

The dress may look familiar, and that's because Kate has worn this silhouette from this designer before. It seems to be one of the "tricks" to the princess's style, that she knows what she likes, and what works for her, and seeks to duplicate it. See below for the dress from today and the style Kate has worn to two St. Patrick's Day parades in the past (pictured here in 2012).

It's not the first time Kate's found a dress she loved and requested it in more than one color -- and in fact, not the first time she's done it with Emilia Wickstead. Below, a pretty pleated creation that she first wore in 2012 in pink -- to an event with William and then to a garden party -- and then again in 2014 in teal while on the royal tour of Australia and New Zealand.

Today, Kate paired the dress with her pointed L.K. Bennett Fern leather pumps in Trench, which retail for £195 ($250), and are still available in every size.
