Jeans and a blazer - 7 outfit ideas from a fashion editor

1. How to style jeans and a blazer for the office

As office dress codes have relaxed over the years, jeans are becoming much more acceptable in the workplace. To keep it looking professional, avoid any distressed detailing or rips in your jeans as this can make them feel too worn and scruffy. Instead, look to dark-wash or black jeans and opt for a slim, straight, or tailored cut rather than baggy or slouchy styles, which are largely too casual for office environments. Neutral blazer colours such as grey, beige, and black will always feel meeting-ready. Finish with a smart shirt, a fitted tee, or a knit for a simple but polished outfit. Regarding the best footwear for keeping your look office-ready, jeans and heels are a fail-safe.

“For the office, you can pair dark wash skinny or straight leg jeans with a solid colour blazer and a blouse. This keeps it simple and professional so your colleagues are not distracted by your outfit when you are working or presenting,” says Tiffany S. Walker, founder & head designer at Pink Lucy Fashion House.

2. How to style jeans and a blazer for a date outfit

Whether you need help with what to wear on a first date or a tenth one, date night dressing can be a tricky one to master, but jeans and a blazer nail that effortless aesthetic whilst still looking put-together. Offering a good opportunity to inject some personality into your look and be a bit more playful with your styling, go bold and try a more colourful blazer, add a sparkly bag, or try a vibrant shoe for something more subtle. For daytime dates, the best white trainers will keep the look low-key and comfy. Swap for a low kitten heel or mule in the evening and add a silky cami underneath.

3. How to style jeans and a blazer for casual wear/weekend

Whether it’s a weekend walk or Sunday brunch, there are no rules when it comes to figuring out how to wear a blazer with jeans for a smart casual outfit idea. Play with proportions and try an oversized blazer with some trending barrel leg jeans.

"Oversized and boyfriend-fit blazers look good with other oversized items, so throw on your favourite boyfriend or wide-leg jeans for a super casual but cool look. I would style this outfit with a relaxed-fit shirt, chunky jewellery, and a sleek, pulled-back bun,” says Megan.

For something more streamlined, add a fitted tee, some high-waisted jeans, and a belted blazer to create a more curvaceous silhouette. Finish with some chunky dad trainers or sporty sandals for an achingly cool look you’ll want to wear on repeat.

4. How to style straight leg jeans and a blazer

Most jeans will look good with a blazer, but it doesn’t get more classic than a pair of straight-leg jeans. The perfect combo to take you from desk to drinks, opt for a cropped pair or roll up the hem of your jeans to show off your shoes and create a flattering ankle-length finish. Finish with open-toe sandals for summer or woven ballet flats for a contemporary spin.

5. How to style skinny jeans and a blazer

Skinny jeans have returned as part of the fashion trends of 2025, and if you’re a fan of the figure-hugging style, a blazer is great for keeping them feeling elevated and on-trend.

If you're wondering how to wear a blazer with jeans that are slim fitting or skinny, balance the proportions and opt for a boyfriend double-breasted blazer or an oversized fit to offset the slim-fit jeans and create a more relaxed look that still feels polished. Alternatively, add a belt if you want to accentuate your shape. In the summer, opt for lightweight materials such as breathable linen or cotton.

"At the moment, I'm loving a belted blazer, which certainly makes a statement. To keep the focus on your top half, I would pair this with some black, skinny jeans, which will also create an ultra-feminine and interesting silhouette, reminiscent of the 1990s. For this look, I would keep the accessories to a minimum and throw on some classic closed-toe heels for a super chic feel,” explains Megan.

6. How to style wide leg jeans and a blazer

Who doesn’t love a pair of the best wide-leg jeans? With serious leg-lengthening powers and comfort guaranteed, wide-leg jeans are no longer a fleeting denim trend but a firm style staple. A structured or cropped blazer looks oh-so-chic with a pair of wide-leg jeans and helps to readdress the balance of the wider fit by offering a tailored element to proceedings. Try choosing platformed sandals or chunkier shoe styles for even more balance.

7. How to style baggy jeans and a blazer

A weekend look you can always rely on, baggy denim jeans and a blazer, which is the epitome of high-low cool. Take things to the extremes and go fancy on the blazer, think bold colours or loud heritage prints like gingham. Add a bit more structure and opt for a cropped blazer and some high-waisted slouchy jeans to help draw in the waist.

“When deciding on the type of jeans to wear with a blazer, consider the fit and wash of the jeans. Dark wash, skinny, or straight leg jeans and tailored blazers are generally more office-appropriate, while jeans with a lighter wash or distressed details with crop or oversized blazers are better suited for casual occasions. Most importantly, ensure the fit focuses on your body type for the best results!” says Tiffany.
