The Best Denim Brands Worth Investing In (And How to Find Your Perfect Fit)

Denim is a cornerstone of every wardrobe. Whether it’s the perfectly worn-in jeans you wear every weekend or a structured denim shirt that gives edge to a casual outfit, investing in the right denim is about more than just aesthetics—it’s about quality, fit, and longevity.

But finding your perfect pair can feel like a minefield. Sizing varies dramatically from brand to brand, country to country, and even across collections. That’s where Tellar.co.uk—the UK’s leading free sizing tool—comes in. With one-time login, body measurement matching, and access to 1,500+ brands, you’ll never need to second-guess a size chart again.

So, let’s explore the best denim brands worth your attention, whether you're after timeless classics or trend-driven silhouettes.

1. Levi’s

Best for: Iconic styles and global recognition

You can’t talk about denim without mentioning Levi’s. Founded in 1853, the brand pioneered the modern blue jean, and its 501 Original is still one of the most recognisable styles in the world. Their fits range from skinny to wide leg, and recent sustainability efforts include water-saving practices and recycled fibres.

Sizing Tip: Levi’s fits can vary depending on the cut—501s run straighter, while the Ribcage and Wedgie styles are snug on the waist.

👉 Use Tellar.co.uk to compare your body measurements against Levi’s size chart and avoid a wrong fit.

2. AG Jeans

Best for: Premium fabrics and polished finishes

If you’re looking for luxury denim that feels as good as it looks, AG Jeans is a go-to. The brand blends European craftsmanship with LA ease, offering premium stretch denim with clean lines. AG is particularly popular for its comfort and sleek silhouettes, often preferred for work-to-weekend styling.

Key Picks: The Farrah Skinny, Ex-Boyfriend Slim, and Prima Cigarette leg.

Size Note: Runs true to size, but slimmer fits can feel snug initially. Measure before you buy with the Tellar.co.uk printable measuring tape.

3. Frame

Best for: Modern silhouettes and fashion-forward styling

Founded in London and crafted in LA, Frame is a celebrity-favourite brand known for modern cuts and luxury touches. The Le Skinny de Jeanne and Le Original are wardrobe staples, especially for fashion lovers who lean towards elevated basics.

Styling Tip: Great for tall women—Frame has longer inseams across many styles.

Pro Tip: Brands like Frame tend to run small at the waist. Tellar can help you decide whether to size up based on your hips or waist ratios.

4. Nudie Jeans

Best for: Sustainability and raw denim purists

If you’re seeking ethically made jeans with real denim character, Nudie Jeans from Sweden is your brand. They offer free repairs for life, organic cotton only, and even resell second-hand jeans.

Fit Guide: Raw denim fits tighter at first and softens with wear. It’s designed to mould to your body, so start with your exact size. If in doubt, use Tellar.co.uk to get it right from the start.

5. Re/Done

Best for: Vintage denim lovers

Re/Done reworks vintage Levi’s into new fits, making every pair unique. They offer both one-of-a-kind reworked pieces and their own line of original cuts using rigid denim.

Why We Love It: You get the vintage look without the thrift-store hunt.

Note: Reworked denim varies widely in sizing. Use your measurements rather than relying on the label—and confirm via Tellar.co.uk's personalised recommendation.

6. Citizens of Humanity

Best for: High-rise lovers and tailored styles

Known for its dedication to craftsmanship and clean aesthetics, Citizens of Humanity is one of the few brands that cuts and sews in its own LA facility. Their denim is consistently high quality and ultra-flattering across body types.

Size Insight: Their Rocket and Daphne fits are bestsellers for a reason—but they can be snug on the waist. Measure carefully to ensure a smooth fit.

7. Weekday

Best for: Affordable, trend-driven denim

A Scandinavian brand under the H&M group, Weekday offers modern, minimalist denim at accessible prices. Their fits include baggy, straight, and cropped cuts for all genders, and they use sustainable cotton across many lines.

Bonus: Excellent gender-neutral options.

Fit Advice: European sizes differ—Tellar.co.uk helps translate EU to UK/US sizing so you don’t have to guess.

8. Goldsign

Best for: Designer luxury and editorial style

Owned by Citizens of Humanity, Goldsign offers minimalist high-end denim that looks like it walked off the pages of Vogue. Think strong silhouettes, heavyweight denim, and clean tailoring.

Fit Overview: These styles often have minimal stretch—perfect for structure but not very forgiving. You must get your waist and hip measurements right.

9. Everlane

Best for: Transparency and modern basics

Everlane is the leader in ethical fashion transparency. Their denim is made in eco-friendly factories and priced fairly. With a focus on essentials, their cheeky straight jean is particularly flattering.

Sizing Tip: Many styles have a generous hip curve and run true to size. Use Tellar’s profile creator to store your measurements and make sizing easier across brands like Everlane.

10. Wrangler

Best for: Rugged denim and western-inspired wear

Wrangler may be known for workwear, but their modern collections offer stylish takes on cowboy-cool denim, with great durability. Their high-waisted mom jeans and bootcuts are making a big comeback in fashion circles.

Fit Insight: Slightly roomier in the thighs than Levi’s, great for curvier builds.
