Matteau Sizing Guide: How to Find Your Perfect Fit and What to Buy

Matteau, the Australian label known for its minimalist resortwear and elevated swim, has become a staple for those who love clean silhouettes and timeless design. But despite the brand’s refined simplicity, finding the right size can be surprisingly complex—especially when shopping from the UK.

This guide breaks down everything you need to know about Matteau sizing, which pieces are worth investing in, and how Tellar.co.uk helps you get it right the first time—with no more returns, size confusion, or expensive mistakes.

Why Matteau Has a Loyal Following

Founded by sisters Ilona Hamer and Peta Heinsen, Matteau is built on the idea of quiet luxury: minimalist cuts, neutral tones, and sustainable practices.

Its reputation has grown across:

Swimwear that flatters without overexposure
Tailored separates with a relaxed, coastal feel
Effortless dresses ideal for resortwear or city styling

But while the aesthetic is simple, Matteau’s sizing is nuanced—especially with international conversions and body proportions.

Does Matteau Run True to Size?

The general answer: Matteau runs slightly small, especially in swimwear and structured tops.

Product Category	Sizing Notes
Swimwear	Fits snug and is designed to stay in place—consider sizing up if you’re between sizes or have a larger bust
Dresses	Often cut narrow in the bust, more relaxed through the body
Trousers/Shorts	True to size, but high-waisted cuts can feel tight at first
Shirts and Tops	Slightly structured, may require sizing up for broader shoulders or bust

Because Matteau uses Australian sizing, UK shoppers often misinterpret the label sizes—leading to incorrect purchases. Fortunately, Tellar.co.uk simplifies this instantly.

How Matteau Sizes Compare to Other Brands

Here’s a quick comparison for common UK shoppers:

Your Size in UK High Street	Likely Matteau Size (AU/US)
UK 8	AU 8 / US 4
UK 10	AU 10 / US 6
UK 12	AU 12 / US 8
UK 14	AU 14 / US 10

Note: Swimwear runs smaller than ready-to-wear. If you're a UK 10 with a fuller bust, you may want an AU 12 in swim tops.

What’s Worth Buying from Matteau?

1. The Square Neck Crop Top (Swim)

A best-seller with minimalist lines and medium coverage. Ideal for small to mid busts. For larger busts, consider the Tri Crop Top with more support.

2. High Waist Brief

This style gives flattering tummy coverage without sacrificing comfort. Slightly compressive fit—size up if unsure.

3. The Tiered Sundress

Matteau’s iconic flowing maxi—lightweight, soft cotton, and cut to flatter a variety of body types. True to size through the hips but check bust room.

4. Wide Leg Trousers

Relaxed tailoring with coastal cool. These are perfect for resort layering or elevated daily wear.

What If I'm In Between Sizes?

Tellar.co.uk accounts for:

Body proportions (e.g. broader hips or narrow waist)
Fabric stretch
Product cut
Brand inconsistencies

Rather than picking based on a general chart, we give you a size based on your actual body data. You can even choose your preference: more fitted or relaxed.

Matteau for Different Body Shapes

Matteau’s minimalist cuts don’t mean one-size-fits-all. Here’s how they perform on different body types:

Body Shape	Style Advice
Hourglass	Size up in tops, especially swim styles; bottoms often true to size
Pear-Shaped	High-waist briefs and flowy dresses work well; watch for narrow tops
Athletic	Matteau fits well, especially in straight-leg trousers and bandeau tops
Petite	Check length—many dresses run long. Use Tellar to adjust for height automatically
