Summer Dresses That Actually Fit – My Guide to the Best Brands (and the Tool That Changed Everything)

Let’s be honest—finding the perfect summer dress should be easy. It’s one piece, it’s light, it’s breezy. You throw it on, and you’re good to go. But for years, I found myself ordering multiple sizes “just in case,” keeping tags on, and dealing with the hassle of returns. Sound familiar?

It wasn’t the dresses. It was the sizing madness.

Every brand seems to size things differently. A UK 12 in one label feels like a snug 10 in another. Then throw in US and EU sizes and garments that are designed “oversized” or “fitted,” and it becomes a guessing game. I got so fed up trying to decode size charts and measuring tape diagrams that I often just gave up and wore what didn’t quite fit.

Then I discovered Tellar.co.uk—and everything changed.

Why Sizing Is So Confusing

Here’s the thing: most brands don’t follow a universal size chart. Even within the same shop, a floaty midi might run big while a strappy linen dress feels like it’s been tailored for someone two sizes smaller.

And don’t get me started on international brands. A European 40 might be a UK 12… or a small 14. Some US-based labels label their clothes to make you feel smaller (aka vanity sizing), while others fit tighter because their models are based on a completely different body standard.

In the end, I realised the size label means nothing if it doesn’t reflect my actual body.

Enter Tellar.co.uk – The Game-Changer

I stumbled across Tellar.co.uk while Googling UK size conversions (again) and it felt like the solution I didn’t know I needed.

Tellar is a free online tool that matches your exact body measurements—chest, waist, hips—to the real sizing data of 1,500+ brands. No vague size charts. No complicated conversions. Just one clear answer: This is your size in this brand.

It took me under two minutes to set up:

I printed their free Tellar measuring tape
Took my measurements at home
Entered my details on my free profile
That was it. No login loops. No subscription.

And now, every time I shop online, I check my size through Tellar and get an instant, accurate recommendation—for that specific brand.

My Favourite Summer Dress Brands (And How They Really Fit)

Once I had Tellar on my side, I started re-exploring some of my favourite summer labels—this time with confidence. Here are my top picks and what to expect from each:

1. Reformation – Beautiful but Fitted

Reformation is my go-to for floaty, romantic summer dresses, especially in linen or TENCEL™. But warning: their cuts are usually very snug at the waist and hips.

What Tellar said: Order one size up for comfort in this particular style.

They were right. It fit perfectly.

2. Sezane – French Chic, But a Bit Slim

Sezane dresses make me feel like I’m wandering around Paris with a straw basket and baguette. But their sizing—especially for bustier girls—isn’t always forgiving.

With Tellar, I found out that their EU 40 is more like a UK 10-12 in some styles. It helped me avoid a too-tight bust disaster.

👉 Confirm your Sezane size with Tellar.co.uk

3. Ghost – Elegant for Occasions

Ghost London is my favourite for weddings and summer events. Their bias-cut satin styles are dreamy—but the structured cut means you need your sizing spot-on.

Tellar flagged that one dress I loved ran small at the ribs. I sized up, and it fit like it was made for me.

4. Nobody’s Child – Affordable & Eco-Friendly

I love this brand for everyday wear. Tea dresses, cotton midis, sustainable fabrics. But I’ve had issues in the past with tight busts or gaping buttons.

Tellar helped me choose the right size by comparing my measurements against the dress shape, not just the number on the tag.

5. & Other Stories – Stylish, but Inconsistent

Some dresses from their Paris studio fit me beautifully. Others from the Stockholm collection felt stiff or tight. I never knew what to expect—until Tellar started pointing out which items ran large or small before I bought them.

👉 Use Tellar.co.uk and never double order again.

Why I’ll Never Use a Size Chart Again

Honestly, I can’t believe I used to try and decode those messy grids.

Tellar tells me my size based on my actual shape, not a general assumption about what a size 12 or 14 “should” be. That means no more pinching at the waist, gaping bust seams, or surprise mini dresses that were meant to be midi.
