There was a time not too long ago when nearly every single outfit I wore included an oversize blazer. But over the last few years, I’ve begun to look for other alternatives that don’t feel so safe and expected. And the only real contender I’ve found along the way just got Kate Middleton‘s royal stamp of approval. (Talk about validation.)

At a celebration for the reopening of the National Portrait Gallery in London this week, the Princess of Wales wore a black-and-white ensemble by Self-Portrait (which is still available in limited sizes at Matches) with Aquazzura pumps and a Chanel clutch. At first glance, her dress appears more like a jacket and skirt, with the top half being the outerwear style I’ve slowly but surely been replacing my endless big-blazer collection with: the lady jacket. 

Unlike a typical blazer, lady jackets are cropped and fitted, making them appear chicer and more formal. Many are made out of tweed or bouclé, though J.Crew’s become famous for designing them with Italian wool and cotton, thus offering up a more casual alternative. While Middleton’s take looks more like a suit, my favorite styling method is to pair one with loose denim, ballet flats or kitten-heel pumps, and a simple tee or tank. But really, you can’t go wrong either way. See her look for the reopening and shop the trend below. 

On Kate Middleton: Self-Portrait Metallic Bouclé and Chiffon Midi Dress ($327); Chanel Classic Wallet on Chain ($3350); Aquazzura Bow Tie 105 Suede Pumps

This on-sale Zara jacket is selling out fast. 

If you look close enough, you’ll notice this style features all-over sequins. 

The buttons on this jacket make the piece 10 times chicer. 

I do, indeed, want one in every color. 

Those boxy shoulders add a masculine touch I didn’t expect to love so much. 

This style has a bit of the military look that Yves Saint Laurent made appear chic and elegant in the ’80s and ’90s. 

Prepare for compliments when you pair this $60 blazer with jeans and a T-shirt. 

No, but actually, I’m obsessed. 

Are you starting to see the appeal yet? 

The styling possibilities really are endless with a piece like this one. 

The matching skirt is irresistible too. 

Quick, before the last few styles sell out. 

If you ask me, Liberowe makes the chicest lady jackets of all.
