Icon Denim LA Sizing: Does It Run True to Size?

By Ella Blake — Fashion Stylist | Tellar Fashion Hub — Always honest, unbiased & unsponsored

Icon Denim LA sizing runs small to true to size depending on the style — but here's the catch: the variation between styles is significant enough that you genuinely cannot assume the same size across their range. As someone who has tested a fair few Los Angeles denim brands, this one requires a bit of homework before you buy.

I first came across Icon Denim LA when I spotted their wide-leg silhouettes all over Instagram a couple of years back — that classic, effortless LA-girl aesthetic with the high waist and the draped leg. Ordered my usual size. Couldn't get them over my hips. Lesson very much learned.

The Brand in Brief

Icon Denim LA is a Los Angeles-based label with a cool, considered approach to denim. They focus heavily on cut and proportion — think clean lines, a relaxed-but-polished feel, and styles that look expensive without screaming logo. Their jeans are made from 100% rigid cotton denim, which means no stretch. Zero. That's important to know upfront because it completely changes how you approach sizing.

They do wide leg, straight leg, crop, and flared styles for women, alongside tops and outerwear. It's a cohesive, pared-back range and genuinely lovely — but only if you get the size right.

How Does Icon Denim LA Sizing Work?

The jeans are sized in US numeric sizing — so you're shopping in 24, 25, 26, 27, 28, 29, 30, 31, 32. If you're used to UK sizing (8, 10, 12 etc.) that's already a step removed from what you know. Their own advice is that waist circumference is the most reliable measurement to size by, which I'd agree with entirely for a non-stretch denim. If your waist and hip measurements fall in different sizes, go with whichever is larger — you can always wear a belt, but you cannot magic extra fabric into existence.

Here's how the different styles break down in practice:

Wide leg styles (Poppy, Debby, Iris, Coco, Will): These vary — some are true to size, others run slightly large through the leg. The waist tends to be the sticking point. Measure your waist and match it to the size chart rather than relying on your usual number.
Straight leg (Annie): Generally true to size, but again — non-stretch denim means you want a comfortable fit, not a snug one. There's no give to rely on.
Crop styles (Tiny): These sit lower on the waist, so take particular note of the rise measurement if you're between sizes.
Flared styles: Tend to run small at the waist and hip. Go up at least half a size, and if you're curvier through the hip and thigh, consider going up a full size.
Tops and sweatshirts: Much more forgiving — relaxed fits tend to be true to size or slightly generous. The brand deliberately designs tops with an oversized silhouette.
Structured jackets and blazers: These can feel tight across the shoulders and bust, so if you're broader across the back or have a fuller chest, size up.

My Honest Verdict on the Fit

The rigid cotton construction is both the beauty and the challenge of this brand. Those jeans look incredible — structured, clean, and they hold their shape all day. But unlike a stretch denim that'll accommodate a bit of fluctuation, 100% cotton denim will tell you every morning exactly what size you are. There's something almost old-school about it that I actually respect, but you do need to commit to sizing accurately.

The other thing worth flagging for UK shoppers is that the proportions are cut for an LA body aesthetic — which can mean a slightly narrower hip-to-waist ratio compared to what British brands typically cater for. If you carry your weight in your hips and thighs, I'd go up a size and take in the waist if needed, rather than buying for your waist and fighting to get the jeans on.

The wide-leg silhouettes are the real heroes of the range in my opinion. Paired with a tucked-in linen shirt or a cropped knit, they look genuinely chic — very much that easy, throw-it-on and look sorted energy that's hard to replicate with cheaper fabrics.

Brilliant Alternatives Worth Knowing About

If Icon Denim LA's sizing feels like too much of a gamble, or you simply can't justify the price point right now, here are some brilliant alternatives across different budgets — all worth exploring for similar wide-leg and relaxed denim styles:

High Street & Mid-Range

Mango — consistently one of the best high street options for wide-leg and barrel-leg jeans right now. Their denim quality has improved significantly and sizing tends to be reliable.
Abercrombie & Fitch — genuinely brilliant for jeans. Their 90s Ultra High Rise style in particular is a favourite, and they have a wide range of leg lengths which is rare.
COS — a more minimalist take on relaxed denim. Their wide-leg styles are beautifully cut and the brand tends to size consistently. A solid choice if you love the clean aesthetic.
Massimo Dutti — slightly smarter in feel, great quality denim. If you want the wide-leg look but you're heading somewhere that needs a bit more polish, Massimo Dutti does it well.
Levi's — the original and still one of the best. Their Ribcage Wide Leg style is everywhere for good reason, and because they've been making jeans forever, the sizing is extremely consistent and well-documented.
Whistles — underrated for denim. Their straight and wide-leg cuts are well-proportioned and the quality is excellent for the price point. Very much the kind of brand that quietly delivers.
Me&Em — a brilliant British brand for premium everyday denim. Their jeans are flattering, well-made, and the sizing is true to a UK fit, which makes them an easy win.

Premium & Designer

Citizens of Humanity — if you want the premium LA denim feel that Icon is going for, Citizens of Humanity is the obvious comparison. The Paloma wide-leg in particular is a classic. Their sizing runs true to size and they do half sizes, which is a genuine gift.
Paige — another LA premium denim brand and one that often suits UK body shapes slightly better than some of its competitors. Their Anessa wide-leg style is beautiful and the stretch-blend construction means you get a more forgiving fit.

Independent Picks

Boyish Jeans — a California-based sustainable denim label that nails that relaxed, cool-girl silhouette. They use deadstock and recycled fabrics and the quality is excellent. Sizing tends to be true to size with a slight relaxed feel.
Outland Denim — an ethical Australian brand with a genuinely considered approach to denim production. Their wide-leg styles are flattering and the brand is transparent about how they size. A great option if provenance matters to you alongside aesthetics.
