What Is Sizing Like at Simona Corsellini?

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

Simona Corsellini sizes run small by UK standards — as a general rule, you should go up one, sometimes two, Italian sizes from your usual UK size. This is a brand that uses classic Italian sizing (think 40, 42, 44) with a close, body-conscious cut, so if you're used to picking up a UK 12 on the high street and grabbing a similar size in a European brand, you may well find yourself reaching for a 44 or even a 46 here.

I discovered Simona Corsellini a couple of years ago while hunting for something a bit different for a winter event — something with more drama than the usual Reiss blazer. I came across one of their double-breasted jackets in a deep teal and was immediately smitten. Then I ordered my "usual" Italian size 42 and it arrived… let's just say it was a great fit if I wanted to channel very-structured-corset energy. Lesson learned: check the measurements, not just the label.

The Brand at a Glance

Simona Corsellini is a Bologna-based Italian fashion house founded in 2015 (originally trading as Space Style Concept, then relaunched under the designer's own name in 2019). It's a brand built on sensual, feminine dressing with an Italian sartorial backbone — think fluid silk blouses, tailored wide-leg trousers, sequin-fringed skirts, and statement dresses with dramatic cuts, plunging necklines and asymmetric details. The price point sits in the premium-to-luxury tier; you're looking at £250–£700+ for dresses and outerwear. It's strictly Made in Italy and the quality absolutely shows.

Simona Corsellini Size Conversion Guide

The brand uses Italian numeric sizing (36–48) alongside alpha sizing (XS–XXL). Italian sizes run roughly 4 numbers larger than UK sizes, but given the brand's fitted cut, I'd strongly recommend sizing up one from your Italian equivalent — especially in tailored pieces and dresses.

Sizing by Garment — What to Know Before You Buy

Dresses & JumpsuitsThis is where sizing consistency matters most, and where the brand's bodycon-leaning silhouettes can trip you up. The dresses are cut to skim the body closely — deliberately so, as Corsellini's whole ethos is about celebrating the female form. I'd always advise sizing up one from your typical Italian equivalent. If you're between sizes, go larger. The fabrics (viscose, satin, jersey blends) have minimal stretch, so there's no forgiving fabric to bail you out.

Blazers & Tailored JacketsBeautifully constructed, but the cut is very sharp and Milanese — narrow through the shoulder and close at the waist. If you have broader shoulders or a fuller bust, absolutely go up a size. Even if the body fits, the shoulder line needs to sit correctly. These are not designed with extra ease.

Trousers & Wide-Leg PantsInterestingly, the trousers — particularly the wide-leg styles — tend to be more forgiving than the tailored pieces. The high-waisted cuts accommodate a range of hip-to-waist ratios reasonably well. That said, I'd still check the waist measurement against the brand's own size chart and err on the side of going up if you're on the cusp.

Knitwear & TopsThe brand's knits have a more relaxed approach; you'll generally find that your standard Italian size or even one down works well here. The cardigans and looser-cut tops are one area where you don't necessarily need to size up — but always check the fabric composition. Less stretch means less room for error.

SkirtsFrom pencil cuts to sequin-fringed minis, the skirts sit close to the hip and thigh. Size up from your Italian equivalent unless you have a very straight figure. The waistbands on the tailored skirts in particular are cut small.

Buying Simona Corsellini in the UK

In the UK, you can find Simona Corsellini on Farfetch, YOOX, and the brand's own website at spacesimonacorsellini.com. Sizing advice on those platforms varies in quality, so always cross-reference your measurements with the brand's own size chart rather than relying on generic conversion tools.

High Street Alternatives — Similar Vibes, Easier Sizing

If the Italian size lottery puts you off, or you simply want to explore a similar aesthetic at various price points, here are my top picks:

High Street

Massimo Dutti — The closest high street equivalent to Italian luxury dressing. Impeccable tailoring, clean lines, and a colour palette that takes itself seriously. Their blazers and trousers in particular share Simona Corsellini's sartorial DNA.
Jigsaw — Quietly excellent British womenswear with a similar appreciation for quality fabrics and unfussy sophistication. Their wide-leg trousers and silk-blend blouses are consistently brilliant.
Reiss — A go-to for that sharp, polished silhouette without crossing into designer pricing. Their tailored dresses and structured blazers hit a similar note to Simona Corsellini's more daywear-appropriate pieces.
Whistles — Understated and elegant, with a great selection of fluid trousers and relaxed-luxe tops. Not as bold as Simona Corsellini, but a brilliant building block for the same kind of wardrobe.
Me&Em — Probably the best British high street equivalent for that put-together Italian woman energy. Their tailoring is exceptional for the price, and the sizing is reliably consistent.
Phase Eight — A brilliant option if it's the brand's evening dresses and occasion pieces that have caught your eye. Phase Eight does occasion dressing with genuine elegance and at a fraction of the price.
Anthropologie — For anyone drawn to Simona Corsellini's more print-forward, textural pieces, Anthropologie has some genuinely beautiful limited-run dresses and blouses with a premium feel.
LK Bennett — For polished dressing that reads as effortlessly Italian without the Italian price tag. Particularly strong on tailored dresses and smart occasion pieces.

Premium

Claudie Pierlot — A French brand with a similar sensibility: feminine, contemporary, and confidently stylish. Their dresses and tailored separates are beautifully made and widely available in the UK.
Ted Baker — For the more embellished, occasion-ready side of Simona Corsellini, Ted Baker delivers consistently pretty results with good sizing options across the range.

Luxury / Designer

Remain Birger Christensen — This Copenhagen-based label shares Simona Corsellini's love of a bold silhouette and statement cut. Known for their puff-sleeve dresses and strong architectural shapes. A fantastic independent find if you're already spending at this level. Stocked at Matches and Selfridges.
Essentiel Antwerp — A Belgian independent brand that has something of a cult following among women who love unapologetically joyful, bold dressing. Think daring prints, confident cuts, and fabrics that actually feel special. Genuinely under the radar, and all the better for it.
