What Is Sizing Like at Sinead Gorey? Your Complete Fit Guide

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

Sinead Gorey sizing runs small to true-to-size — so for the brand's signature bodycon pieces, cutout dresses and form-fitting co-ords, most women will want to size up one from their usual. It's one of those brands where knowing your exact measurements really matters, and I say that from experience (more on that below).

Who Is Sinead Gorey?

If you haven't already fallen down the Sinead Gorey rabbit hole, let me introduce you. She's a South East London-based designer who launched her eponymous label in 2019 and has since built a proper cult following — think Jorja Smith, Abby Roberts, and a very dedicated army of women who like their going-out looks to actually turn heads. The brand is known for those incredible infrared-print bodysuits and dresses (they mimic the look of thermal imaging — curve-enhancing in the most brilliant, slightly surreal way), as well as cutout miniskirts, corset-laced separates and draped satin pieces.

It's not your average high street buy, but it sits at a more accessible price point than most designer labels, which is exactly why so many people are buying it. The aesthetic is part Y2K rave, part London underground — and it's genuinely unlike anything else out there right now.

So, Does Sinead Gorey Run Small?

Here's my honest experience: I picked up one of the brand's printed bodycon midi dresses in my usual size 10, and it was tight — uncomfortably so across the hips. I'd say for the stretch, second-skin pieces (the bodycon dresses, the bodysuits, the printed co-ord sets), go up one size. A size 10 customer would comfortably sit in a 12; a size 8 in a 10.

That said, the brand's newer draped and woven pieces — the asymmetric slip-style dresses, the gathered satin styles — have a bit more give and can be worn true to size. It's very garment-dependent, which is why checking measurements rather than just the label is genuinely worth the thirty seconds it takes.

Sinead Gorey Size Guide

The brand uses standard UK sizing from XS through to L. Here's how that maps across internationally:

My advice: Always measure your hips first. Sinead Gorey's bodycon silhouettes are designed to sit close to the body, and hip measurements are where most women find the pinch point. If you're between sizes, size up — you can always belt a slightly larger dress, but a zip that won't do up is a different story (trust me, I've been there).

Garment-by-Garment Fit Breakdown

Bodycon dresses & printed midi dresses: Size up one. These are designed to be skin-close and there is very little stretch tolerance in the structured fabric.
Bodysuits: True to size for most, but if you're fuller in the bust or hips, go one up. The press-stud gusset can pull if the fit isn't right.
Miniskirts & co-ord sets: Size up one, particularly if you're fuller in the thighs. The structured waistbands on the skirts in particular come up small.
Draped & asymmetric dresses: True to size — these have more fluidity in the cut and the fabric drapes rather than clings, so your regular size should work well.
Corset-detail tops: Size up one. The boning structure gives these a rigid shape and they don't allow for adjustment the way a lace-up corset would.
Tights & accessories: Standard sizing applies here — no need to adjust.

How to Style Sinead Gorey

The brand's pieces are designed to do the heavy lifting — you really don't need much else. A printed bodycon dress wants simple strappy heels and nothing fussy; let the garment be the outfit. For the corset pieces and cutout styles, keep your base layer absolutely minimal (think a flesh-toned seamless thong and nothing else — the whole point is the body on show). I've worn the brand's draped satin pieces to both a gallery opening and a birthday dinner, and they translated perfectly to both. That versatility is what makes it worth the splurge.

In terms of body shape — this brand really works for hourglass and pear shapes. The curve-enhancing infrared prints in particular are designed to elongate and celebrate a defined waist and hip ratio. If you're straighter in silhouette, the draped and asymmetric styles will suit you better than the printed bodycon pieces.

High Street Alternatives to Sinead Gorey

Love the aesthetic but not ready to commit to the price tag? Or just want to build out a full going-out wardrobe around those signature Sinead Gorey pieces? Here's where I'd look:

Topshop — Still one of the best for bodycon dresses with a genuine fashion edge. The going-out edit has real personality and sizes are generous, so a good foil if you've sized up in Sinead Gorey and want to balance the look.
River Island — Brilliant for cutout and ruched dresses at a fraction of the price. Their sizing runs slightly more generously than Sinead Gorey, so check the measurements before ordering.
ASOS — Huge range of rave-adjacent and bodycon pieces. Particularly good for digitally printed and graphic-heavy styles if you're chasing that infrared look for less.
Urban Outfitters — Great for the Y2K-rave crossover moment. Their satin slip dresses and co-ord sets have a similar energy to Sinead Gorey's draped collection.
All Saints — If you love the edgy London feel but want something slightly more wearable day-to-night, All Saints does structured and asymmetric pieces with real quality.
Warehouse — Underrated for occasion-ready bodycon and asymmetric hemlines. Good quality fabrics and consistently flattering cuts.
Oasis — Brilliant for draped and ruched occasion dresses at a mid-range price. Their cut tends to run true to size and is more generous in the hip than Sinead Gorey's own sizing.
Coast — For the more structured, special-occasion side of the Sinead Gorey aesthetic — think corsetry-inspired bodices and sleek column shapes for event dressing.

Two independent brands worth knowing:

Poster Girl London — A brilliant cult London label doing cutout dresses, mesh pieces and going-out styles with a very similar energy to Sinead Gorey. Adored by influencers and stylists alike, and the sizing tends to be slightly more generous. Worth every penny.
Nadine Merabi — Based in Manchester, Nadine Merabi makes spectacular embellished pieces and curve-enhancing occasion dresses. More glamorous than Gorey's rave roots, but with the same commitment to making women look genuinely incredible. A truly special label.

Premium & Luxury Alternatives

If you're looking to invest further up the ladder: Nensi Dojaka and 16Arlington both operate in similar territory — London-based designers making body-celebrating, night-out pieces with serious fashion credibility. For pure sculptural drama, David Koma is the reference point for this type of bodycon architecture. These sit at a higher price point but are genuinely considered investment pieces.
