What Is Sizing Like at Johanna Ortiz?

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

Johanna Ortiz sizing generally runs true to size, but with a very important caveat: the more structured and tailored the piece, the more likely it is to run small — particularly through the bust and waist. If you're shopping her flowing maxi dresses and voluminous silhouettes, you'll likely land in your usual size. If you're eyeing anything with a nipped-in waist, a corset detail, or a fitted bodice, size up. It's the kind of brand where a single size difference can mean the difference between a jaw-dropping dress and a very expensive regret.

I remember the first time I came across Johanna Ortiz properly — not online, but in person at a stylist event in London. Someone walked into the room in one of her signature tiered silk maxi dresses and honestly, every head turned. There's something about the way this brand moves that you can't replicate on a hanger or a screen. It's only when you see it in motion that you understand what the fuss is about. And the fuss, for the record, is entirely justified.

The Brand in Brief

Johanna Ortiz is a Colombian luxury label founded in Cali in 2003 by its eponymous designer. Inspired by Latin America's lush tropical landscape and rich artisanal heritage, the brand has built its reputation on handcrafted fabrics, bold botanical prints, and silhouettes that feel genuinely celebratory. This is dressing for people who believe that getting dressed should be joyful — floor-length ruffled gowns, exaggerated sleeves, silk georgette in prints that look like they were painted by hand. The label went international in 2014 through Moda Operandi and now stocks through Net-a-Porter, Matches, MyTheresa and Bergdorf Goodman. It is, as price points go, a genuine investment — dresses typically range from around £1,200 to over £2,500 — which makes getting the sizing right absolutely non-negotiable.

How the Sizing Actually Works

The brand uses US sizing (XS through to XL, with some pieces also in numeric 0–14), and on their own website they offer a Find Your Size tool on each product page, which is genuinely helpful. But here's what the size chart won't tell you: the fit varies considerably depending on fabric and construction.

Fluid maxi dresses and tiered skirts: Generally true to size. These styles have the most forgiving construction, and the volume of fabric means there's room to breathe. Measure your bust and hips and go with your standard size.
Structured mini and midi dresses: These run small. The brand itself flags certain styles — like the Gangaway Dress — as running small based on customer feedback, and recommends sizing up. I'd echo that advice strongly, especially if you're fuller in the chest.
Corset and bodice-detail pieces: Size up. No question. These are not forgiving constructions, and in a non-stretch fabric, even a few centimetres of difference matters enormously.
Blouses and tops: Varies by style. Relaxed, oversized silhouettes are typically true to size or generous. Anything with a defined waist or structured shoulder reads small.
Trousers and wide-leg styles: True to size on the leg and hip, but the waistbands can feel snug. If you're between sizes, go up.
Swim and resort pieces: Tend to be true to size, but cut for a slender frame. If you're curvier through the hip, size up for comfort and confidence.

One thing worth knowing for UK shoppers specifically: Johanna Ortiz uses US sizing, so you'll need to convert. A US 4 is roughly a UK 8, a US 6 is a UK 10, and so on — but the brand's proportions don't always follow standard UK conversion charts cleanly, particularly in the bust. Always use your measurements rather than your usual UK number.

What the Fabrics Mean for Fit

This matters more than most brands. A significant portion of the Johanna Ortiz range is made from silk georgette, silk CDC, and other non-stretch luxury fabrics. There is no give. What you put on is what you've got, which is why measuring yourself properly before you buy is absolutely essential. I've seen women size up in stretch-blend dresses from other brands without issue, then find that the same approach doesn't translate when the fabric has zero elasticity. With Johanna Ortiz, the construction carries the garment — so the fit has to be precise.

The upside? These fabrics drape extraordinarily well when the fit is right. A perfectly sized silk georgette maxi dress from this brand is one of those genuinely transformative wardrobe moments. It's worth the effort.

Brilliant Alternatives at Every Budget

Johanna Ortiz is an investment, no question. But the aesthetic — bold tropical prints, flowing silhouettes, statement occasion dressing — is very much having a moment, and there are excellent options at every price point for those who want the look without the four-figure price tag.

High Street & Mid-Range

Anthropologie — genuinely one of the best high street destinations for anyone who loves the botanical, artisanal, free-spirited aesthetic that Johanna Ortiz does at the luxury end. Their maxi dresses and printed midi skirts hit a similar mood at a fraction of the price.
Mango — consistently delivers on occasion-wear dresses with a Spanish warmth to the prints and silhouettes. Their linen and silk-blend maxi styles are particularly good value and photograph beautifully.
Phase Eight — an underrated choice for flowing, feminine dressing. Their occasion and wedding-guest range in particular has some beautifully cut dresses with that effortless, dressed-up-but-not-trying quality that Johanna Ortiz does so well.
Monsoon — this one's obvious, but worth saying: if you love bold prints and flowing fabrics, Monsoon has been doing it for decades. Their embroidered and printed maxi dresses consistently overdeliver for the price.
Ted Baker — brilliant for occasion dressing with a polished edge. Their botanical print dresses and elegant midi styles suit the woman who loves colour and print but wants something she can wear to a garden party or a smart dinner.
Reiss — for the more tailored side of the Johanna Ortiz world. If you love her structured mini dresses and sleek co-ords, Reiss does elevated occasion-wear dressing with excellent construction at a much more approachable price point.
Coast — a strong pick for event and occasion dressing. Coast has improved enormously over the past few years and their evening and occasion ranges now include some genuinely striking pieces in bold prints and luxe-feeling fabrics.

Premium

Zimmermann — the closest aesthetic match at a slightly lower price point. Australian brand, similarly obsessed with botanical prints, voluminous sleeves, and occasion-worthy dresses. If you love Johanna Ortiz's world, Zimmermann is the obvious next stop.
Self-Portrait — a London-based label that does beautiful occasion dressing, often in bold prints and cut-work fabrics. Sizing tends to run true to size and they cater well to UK body shapes.

Independent Picks

Agua by Agua Bendita — a Colombian label, fittingly, and one that shares Johanna Ortiz's DNA in terms of vibrant prints, artisanal craftsmanship, and sun-drenched tropical energy. Slightly more accessible in price point and brilliant for resort and holiday dressing.
La Double J — a Milan-based independent label steeped in Italian print heritage and bold, joyful colour. Their archive-print dresses and co-ords have a similar celebratory quality to Johanna Ortiz, and they've built a devoted following among fashion editors for exactly that reason.
