Kate Middleton's French Sister-in-Law Has Incredible Dress Sense

Kate Middleton's sister Pippa never needed an introduction again after that bridesmaid dress, but now there's yet another chic member of the family to keep an eye on. In September last year, Alizee Thevenet married Kate and Pippa's brother, James Middleton, and she has a cool, relaxed kind of style that I think you'll love. Thevenet is French, works as a finance director in London, and from the looks of her Instagram, happily co-parents James's five dogs. Talk about goals.

Thevenet and Middleton have attended all manner of events since becoming betrothed; everything from a carol service at Westminster Abbey to this year's Wimbledon. One thing has remained consistent at each do: Thevenet's personal style. She's donned some ultra-chic looks that we thought were worth talking about, incorporating pieces from well-known Parisian brands and emerging independent labels. Scroll down to see our favourites, plus the pieces you need to recreate her look.

1. Trench Coat + Cowboy Boots

Style Notes: This outfit, sported by Thevenet as she attended a Peruvian Connection event, is simultaneously classic and current, incorporating two hugely relevant items: a trench coat and cowboy boots.

2. Houndstooth Suit

Style Notes: It's always refreshing to see a celebrity wearing an affordable brand. In this case, it's a houndstooth Sézane suit, and devastatingly, it's no longer in stock. That being said, we did hunt down some equally chic alternatives...

3. Printed Co-Ord + Bucket Bag

Style Notes: Thevenet was the talk of Wimbledon when she wore this beautiful co-ord, designed by Australian label Scanlan Theodore. A pair of oxblood boots would look just as chic with this ensemble.

Style Notes: All-over florals are incredibly elegant, and there's something so vintage about this maxi dress. The gold touch adds a contemporary flair.

5. White Tailoring

Style Notes: Someone who can pull off all-white—especially when carrying a glass of wine!—is as chic as it gets, as far as I'm concerned. I love the relaxed fit of this tailored set.

6. Midi Dress + Nude Heels

Style Notes: Thevenet was surely the best-dressed wedding guest in this paisley-print midi dress, styled with simple nude pumps, a gold-trimmed clutch and a woven boat hat.

7. Burgundy Blazer + Mini Skirt

Style Notes: I'll be recreating this look at the earliest opportunity. The blazer combined with the short hemline and black ankle boots is all kinds of cool.

Associate Director, Fashion News

Erin got her start as a Who What Wear intern over 13 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2016, where she currently holds the title of Associate Director of Fashion News (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Meghan Markle and Kate Middleton stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible. Outside of work, she loves tennis, classic rock, traveling, and smothering her dog with affection.
