What Is Sizing Like at Girl In Mind? An Honest Stylist's Guide to the Fit

By Ella Blake – Senior Fashion Stylist & Founder | Tellar – Always honest, unbiased, & unsponsored post

Here’s the short answer: Girl In Mind comes up true to size on its relaxed, stretchy and wrap styles, but its fitted bodycon and occasion dresses run small – particularly across the bust and hips. So if you’re between sizes, fuller-chested or curvier through the hip, size up. After years of styling clients for weddings, races and party season, this is the brand I get asked about constantly, mostly because the fit is brilliant when you get it right and frustrating when you don’t. Let me save you the guesswork.

So, Does Girl In Mind Run Small?

Girl In Mind is a London label built on celebrity and catwalk-inspired glamour – think bold prints, ruched bodycon, plisse midis and embellished party numbers. That design DNA matters, because heavily fitted, curve-hugging styles are simply less forgiving than a floaty wrap dress. The brand drafts its samples on a UK size 8, and the cut is on the slim side of the high street. As a rough anchor, a Girl In Mind dress sits close to an ASOS or Boohoo 10, but it can pull tighter through the chest and hips depending on the fabric.

Fit by Style – What to Expect

The single biggest mistake I see is treating every Girl In Mind piece as one size. The fit genuinely changes by style:

Bodycon & ruched dresses: The signature look, and the one that runs smallest. Lovely and sculpting, but tight on the bust for anyone above a C cup – size up if in doubt.
Wrap & belted dresses: Far more forgiving. The tie cinches the waist and skims the hips, so stick to your usual size, even if you’re between two.
Plisse & pleated midis: A little stretch built in, so generally true to size unless the bodice is fitted.
Knitwear: Newer and deliberately relaxed. Size down if you want a closer fit; keep true to size for that slouchy, layered look.
Jumpsuits: Check the torso length if you’re tall – the rise can sit short on longer bodies.

A Fashion Fail (and a Win) I Won’t Forget

I’ll be honest with you. The first Girl In Mind dress I ever bought was a ruched bodycon for a summer wedding, and I ordered my “safe” size out of habit. It zipped… technically. I spent the whole reception holding my breath and refusing the canapes. Lesson learned. The win came a year later: a wrap-style floral midi in my normal size that fit like it was made for me, and I’ve worn it to three events since. The difference wasn’t the size on the label – it was the cut. That’s the whole game with this brand.

How to Nail Your Girl In Mind Size

Always buy for your largest measurement – usually bust or hips on fitted styles.
Read the style notes: Girl In Mind flags whether items run small, large or true to size, which is genuinely useful.
For an occasion dress you can’t risk getting wrong, order your usual size and one up, then return the loser.
If you know your size in ASOS or River Island, use that as your starting point rather than guessing.

Where Else to Shop for the Girl In Mind Look

If you love the glamorous, occasion-led aesthetic, here are the brands I send clients to, sorted by budget.

High Street

River Island – The closest direct rival for trend-led party and bodycon dresses at a similar price.
Coast – A genuine occasion-wear specialist; brilliant for weddings and races with a slightly more structured fit.
Oasis – Feminine, print-heavy going-out dresses that echo the Girl In Mind mood.
Warehouse – Sharp, fashion-forward event pieces, often with a cleaner, more grown-up edge.
Monsoon – My go-to for embellished and beaded occasion dresses when you want a bit of sparkle.
Phase Eight – Reliable for flattering occasion midis if you prefer a more generous, true-to-size cut.
Next – Actually stocks Girl In Mind alongside its own strong occasion range, so handy for comparing fit.

Premium

Reiss – Elevated, beautifully tailored occasion dresses that hold their shape and last for years.
Ted Baker – Bold florals and statement prints – the natural step up if it’s the Girl In Mind print energy you love.
Whistles – For a more minimal, modern take on event dressing when you want understated over glam.

Luxury / Designer

Max Mara – Investment occasion dressing with impeccable cut and timeless fabrics.

Two Independent Brands Worth Knowing

Never Fully Dressed – An independent London label with joyful, body-confident prints and wrap dresses that flatter a real range of shapes. A fantastic Girl In Mind alternative with more size inclusivity.
Sister Jane – A small independent known for romantic, whimsical occasion pieces with gorgeous detailing for anyone after something a little different.
