What Is Sizing Like at GCDS? Your Complete Fit Guide

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

GCDS runs small — as an Italian brand, it uses Italian sizing, which typically comes up one to two sizes smaller than what you'd expect from UK high street labels. If you're a UK 10, you'll almost certainly need a 44 or a UK 12 equivalent. Size up, and don't skip the size chart.

I'll be honest with you: the first time I ordered from GCDS I was completely blindsided. I'd been browsing one of their crystal-trim crop tops on Farfetch, feeling very grown-up about my potential luxury streetwear moment, and ordered my usual size. Reader, it did not arrive in my usual size. Or rather, it arrived — it just didn't fit. It was at least a full size too small, and I had to go through the faff of a return. Lesson learned. GCDS is Italian made, Italian cut, and you need to think Italian sizing from the very start.

Who Is GCDS, and Why Does It Matter for Sizing?

GCDS — which stands for Giuliano Calza Design Studio, though fans also know it as "God Can't Destroy Streetwear" — was founded in Milan in 2015 by designer Giuliano Calza. It's grown into one of the most distinctive names in Italian luxury streetwear: bold graphic logos, pop culture collaborations (Hello Kitty, Polly Pocket, Dracula — yes, really), crystal-embellished mini dresses, oversized hoodies, and leather separates that walk the line between maximalist street style and genuine fashion-week credibility.

The brand produces everything in Italy, which means it uses traditional Italian sizing throughout. This is important. Italian sizing has its own system entirely, separate from the UK or standard European conventions, and it runs noticeably smaller. It's not a brand quirk or a design choice — it's simply the sizing standard used across Italian fashion houses, from accessible contemporary labels right up to the big luxury names.

Understanding Italian Sizing: The Basics

Italian clothing sizes for women use a numerical system that can look confusing at first glance. Here's a simple conversion guide to help you find your GCDS size:

UK SizeItalian (GCDS) SizeEU SizeUS Size638342840364104238612444081446421016484412

The general rule: add roughly 32 to your UK size to get your Italian equivalent. So a UK 10 = Italian 42. That said, I'd always recommend measuring yourself and cross-referencing against the official GCDS size chart, because even within Italian sizing, luxury brands sometimes cut smaller still.

Does GCDS Run True to Size, Small, or Large?

GCDS runs small by UK standards — consistently. This is partly the Italian sizing system at work, and partly the brand's design language. A lot of their pieces — particularly the fitted dresses, tailored trousers, and anything with a structured cut — are intentionally close-fitting. The proportions are designed for a Mediterranean body standard that tends to be narrower across the shoulders and through the bust than typical UK sizing assumes.

Here's my honest breakdown by garment type:

Fitted dresses & mini dresses: Size up by one full UK size minimum. The cuts are snug and structured; there's very little ease built in. If you're between sizes, go up.
Oversized hoodies & sweatshirts: These are designed with a deliberately relaxed, drop-shoulder silhouette, so you have slightly more flexibility. Sizing up is still usually wise, but some customers find their true Italian size works here. Check the specific measurements rather than guessing.
Crop tops & jersey pieces: Size up. These are cut close to the body and have very little stretch. I'd go a size up here without hesitation.
Trousers & jeans: GCDS often uses Italian numeric sizing for denim. Add 14 to your US waist size to find your Italian equivalent — so a 28" waist would be a 42 in Italian sizing. If in doubt, size up.
Outerwear & tailored coats: Definitely size up, and potentially two sizes if you plan to layer underneath. Italian tailoring cuts closely through the shoulders and chest, and there's nothing worse than a beautifully cut coat you can't actually button.

Tips for Getting Your GCDS Size Right

Measure yourself before you order. Bust, waist, and hips — then compare against the GCDS size chart on their website. Don't rely on what you "usually" take; Italian sizing makes that approach unreliable.
Check the product-specific measurements. Farfetch and YOOX often list garment measurements alongside the size chart — this is gold. Comparing the actual garment width to your own measurements is the most accurate method.
Read customer reviews. Shoppers consistently flag sizing on GCDS pieces. If a product has reviews, check them for fit comments. "Runs small — size up" is a phrase you'll see regularly.
If you're in between sizes, always go up. GCDS pieces are not the kind of clothes you want straining across the shoulders or gaping at the zip. A slightly looser fit is far more flattering than something too tight.
Check the return policy before buying. Buying from Farfetch? Returns are usually straightforward. Buying direct from the GCDS website? Make sure you're clear on their policy before hitting purchase.

Shoes and Accessories: Does the Sizing Issue Apply?

For GCDS footwear — and they do some brilliant logo slides and sneakers — Italian shoe sizing is generally considered true to length, though the fit tends to be narrower than UK lasts. If you have wider feet, consider going up half a size. Standard Italian shoe sizes correspond closely to EU sizing, so use your EU shoe size as your starting point.

Bags and accessories are, of course, one-size, so no conversion anxiety required — and GCDS's heart-shaped bags and logo pieces are honestly some of the most fun accessories going right now.

Alternatives to GCDS: High Street & Premium Options

GCDS pieces are an investment — we're talking luxury price points. If you love the bold streetwear aesthetic but want to explore similar vibes at different budgets, here are my picks:

High Street

Urban Outfitters — Genuinely the closest high street match to the GCDS energy. Graphic tees, bold logo pieces, playful pop-culture references, and a strong streetwear-adjacent edit. Great for testing the look before committing to designer prices.
ASOS — The sheer range here means you'll almost always find something that captures the maximalist streetwear mood. Their own-brand pieces and curated designer edit are both worth a browse.
Zara — Zara frequently drops Italian-influenced pieces with similar fitted cuts and bold styling. Their embellished and crystal-trim options are particularly GCDS-adjacent.
All Saints — For the darker, edgier side of GCDS. All Saints does graphic print pieces and leather-adjacent separates that have a similar mood without the luxury price tag.
Topshop — Now available through ASOS, Topshop still delivers on bold trend pieces and fun graphic options that complement the streetwear aesthetic beautifully.
H&M — Brilliant for affordable graphic logo tees and streetwear basics. The quality isn't luxury, but for trend-testing the aesthetic before spending big, it's hard to beat.
Mango — Mediterranean roots, trend-led cuts, and some genuinely beautiful embellished and structured pieces at a fraction of the GCDS price. Their dresses in particular often have a similar fitted Italian quality feel.
Anthropologie — For the more eclectic, personality-led side of GCDS. Anthropologie does unique prints and individual styling that shares the brand's refusal to be boring.

Premium

Reiss — Step up in quality with Reiss for clean, Italian-influenced tailoring and contemporary separates. Less maximalist than GCDS, but the craftsmanship sits at a similar premium level without the street art references.
Ted Baker — For the more embellished, jewel-toned, occasion-led side of GCDS — Ted Baker does crystal-embellished details and bold print pieces at accessible luxury pricing.

Luxury / Designer

Moschino — The closest spiritual cousin to GCDS at full luxury level. Camp, bold, logo-heavy, and deeply Italian. If GCDS is your thing, Moschino's archive and mainline pieces will speak your language entirely.
Versace — For the logo-print and maximalist side of GCDS, Versace's Jeans Couture line sits at a similar creative space and price point. Unapologetically bold, Made in Italy.

Two Independent Picks Worth Knowing:

Lazy Oaf — A London-based independent streetwear label that shares GCDS's love of pop culture, bold graphics, and refusing to take itself too seriously. Much more accessible price-wise, but genuinely creative and cult-followed. Sizing is UK standard, which makes a nice change.
Aries — A London streetwear label that bridges the gap between luxury and street in a very similar way to GCDS. Graphic heavy, culturally switched-on, and worn by exactly the kind of people who love GCDS. A brilliant brand to have in your rotation alongside the Italian pieces.
