Mixing the sophistication of tailoring and the effortless style of a slouchy silhouette, an oversized blazer is a true wardrobe staple. One of my favourite transitional pieces, every autumn I throw one on over most of my outfits, adding a longline coat when it gets really cold. From the classic blazer, jeans and white T-shirt ensemble to elevating your athleisure, or wearing one to sharpen up an otherwise feminine midi skirt, they can be worn over just about anything.  Whether you're looking for a chic black oversized blazer, a chocolate brown shade, royal-approved pieces or trending suede, I've found something to suit every outfit.

A capsule wardrobe piece, oversized blazers have been seen on everyone from Princess Kate to Emily Ratajkowski. Proving it's a royal-worthy look, Kate often wears one over a pair of wide-leg tailored trousers for public engagements, while I've spotted Emily nailing casual-cool in several pieces, from black leather to houndstooth, styled with straight-leg jeans and heeled boots. 

Kate Hudson made a case for a pinstripe style worn with jeans and loafers, and Rosie Huntington-Whiteley gave me all of the outfit goals, adding an androgynous edge to her silk midi skirt with her camel blazer. Just add a pair of heels and oversized sunglasses for a very chic autumn outfit. 

How I chose the best oversized blazers

  • Cut: All of these blazers comes in a relaxed oversized cut for that coveted effortless style.
  • Brands: I've only included pieces from team HELLO!'s most loved and trusted fashion brands.
  • Price: From H&M's £44 blazer to real suede styles from Massimo Dutti priced at £349, you'll find options for a range of budgets.

M&S Single Breasted Blazer

Editor's Note:

Super versatile, this black oversized blazer from Marks & Spencer can be worn over your evening outfits or paired with off-duty wide-leg trousers and trainers. A bestseller at M&S, it gets five-star reviews for its high quality and flattering cut.

H&M Oversized Twill Blazer

Reiss Solene Blazer

Editor's Note:

Loved by the Princess of Wales no less, Reiss blazers are an investment piece you can wear every year. The Solene is made from a wool-blend fabric with a twill finish and I'd style it like Kate with wide-leg trousers. This aubergine shade is perfect for the new season.

& Other Stories Wool Blazer

Editor's Note:

& Other Stories' popular oversized blazers are ideal on colder days during the transitional seasons thanks to their cosy wool-blend fabric. Available in several colours, the structured style is fully lined and features duo welt pockets.

Mango Straight Blazer

Editor's Note:

Mango does tailored pieces really well and I love the subtle check design on this oversized blazer. Wear it as the whole power suit, with black tailored trousers, or with vintage-wash jeans.

Boden Woodbridge Cord Blazer

Editor's Note:

Boden's cord blazer is new season perfection. Made from 100% cotton, it's fully lined and features a straight cut with flattering darts and princess seams as well as functional pockets. Size up for a more obvious oversized fit. 

Massimo Dutti Suede Leather Blazer

Editor's Note:

Suede blazers are having a huge moment and I'm obsessed with this one from Massimo Dutti. Made from goatskin leather with a suede finish, it has four-button fastenings, two patch pockets, and topstitching detail.
