What is Rixo Sizing Like? A Complete Guide

Rixo sizing is notoriously inconsistent—you might be a size 10 in one dress and a 14 in another from the same collection. Unlike high street brands where you can reliably grab your usual size, Rixo requires checking measurements for every single piece, as bias-cut silk styles run small whilst wrap dresses and cotton pieces tend to be more forgiving. I learned this the hard way when I ordered three Rixo dresses in my "usual" size 12 for a friend's wedding, only to find one gaping at the waist, another so tight I couldn't zip it, and the third fitting like an absolute dream. It was maddening, expensive with returns, and taught me that with Rixo, your size is more of a starting suggestion than a guarantee.

The Rixo Sizing Reality Check

Here's what nobody tells you about Rixo (the beloved London-based brand creating vintage-inspired dresses with hand-painted prints and 70s glamour): their sizing isn't standardised across their collection. I've spoken to countless women who've had the same experience—ordering multiple pieces in the same size only to find wildly different fits.

This isn't Rixo being careless. It's actually because they use different fabrics and construction methods for different styles. A bias-cut silk dress behaves completely differently on the body than a cotton midi with gathering at the waist. But it does mean you can't approach Rixo shopping the way you'd approach, say, Zara (the Spanish fast-fashion giant known for runway-inspired pieces at accessible prices) or H&M (the Swedish high street staple offering trendy basics and collaborations), where sizing is pretty reliable once you know your number.

How Rixo Sizing Actually Works

Current customer reviews from 2025 paint a mixed picture, and I want to be honest about what you're walking into:

• Some customers report generous sizing – Multiple reviews mention sizing down, particularly in looser styles and wrap dresses

• Others find it true to size – Especially in their structured pieces and maxi dresses

• Several mention inconsistency even within the same size – One reviewer tried four dresses (three size 10s and one size 12) and said none fitted properly

• Petite customers struggle with length – Rixo designs for taller frames (around 5'7"-5'9"), though they now offer a petite collection for women 5'3" and under

The Fabric Factor: Why Your Size Changes

This is the crucial bit. Your Rixo size depends entirely on what the dress is made from and how it's cut:

Bias-cut silk dresses – These are the ones that'll catch you out. Bias-cut means the fabric is cut diagonally across the grain, which makes it drape beautifully but also means it has zero stretch and clings to every curve. If you're ordering one of these, size up, especially if you're busty or have hips. I once ordered the Camellia dress (their iconic style) in my usual size and couldn't get it past my hips. The size up? Perfection.

Wrap dresses – These are more forgiving because they're adjustable at the waist. Generally true to size, and you can cinch them tighter or looser depending on your preference. I find these are the safest Rixo styles to order online.

Cotton or viscose day dresses – More relaxed fit, usually true to size. These tend to have more room through the body and are less unforgiving than the silk pieces.

Blouses and tops – Slightly tailored through the shoulders. If you're broad-shouldered or fuller busted, consider sizing up. I'm neither, and I still find their blouses can pull a bit across the back.

What Other Brands Get Right (That Rixo Doesn't)

Look, I adore Rixo—their prints are unmatched and the quality is genuinely beautiful. But let's be real about where the high street does sizing better.

Whistles (the contemporary British brand known for sophisticated, effortlessly chic pieces) has remarkably consistent sizing. Once you know your Whistles size, you can order with confidence. Same with Jigsaw (the independent British brand offering modern, wearable style with a focus on quality fabrics and tailoring)—I've been the same size there for years.

COS (the minimalist brand from H&M Group delivering architectural, Scandi-inspired pieces) runs consistently true to size, though their cuts can be boxy. & Other Stories (the eclectic sister brand blending Parisian chic with Swedish cool) is more hit-and-miss, similar to Rixo, but at least their prices don't make returns feel quite so painful.

Even Mango (the Spanish high street brand offering sophisticated, trend-led style at accessible prices), which notoriously runs small, is predictably small. You know to size up. With Rixo, you're genuinely guessing each time.

Premium Brands With Better Sizing Consistency

If you're investing in occasionwear at Rixo's price point (£200-400), it's worth knowing that some premium brands offer more reliable sizing:

Reiss (the British contemporary brand known for sharp tailoring and modern elegance) has excellent sizing consistency, especially in their dresses. Ted Baker (the quirky British brand famous for distinctive prints and quality fabrics) can run small in dresses but it's consistent—you learn your Ted Baker size and stick with it.

Me+Em (the London-based contemporary brand creating elevated everyday pieces with impeccable fit) is brilliant for sizing—they're designed with real bodies in mind, and their customer reviews are reliably helpful. Worth looking at if you want that same elevated, feminine vibe as Rixo but with more predictable fits.

Independent Brands Doing It Better

Two independent brands I've found with exceptional sizing consistency:

Kitri (the London-based independent brand creating effortlessly cool, Instagram-worthy pieces) has really nailed their sizing. I'm consistently the same size across their entire range, and their size guides are accurate. Plus their aesthetic has that same vintage-inspired femininity as Rixo.

Résumé (the Danish independent brand offering playful, feminine pieces with Scandi sensibility and vintage touches) is another gem. Their dresses have a similar vibe—romantic, slightly retro, very flattering—but the sizing is far more reliable. I've ordered multiple pieces and never had to return one for fit issues.

My Rixo Sizing Disasters (So You Can Avoid Them)

Let me save you from my mistakes. I once bought a Rixo sequin dress for New Year's Eve without reading reviews. It arrived, I could barely breathe in it, and by the time I sorted a return and reordered the size up, it was sold out. I ended up wearing a dress from Anthropologie (the bohemian American brand offering unique, artistic pieces with vintage charm) instead—lovely dress, but not the showstopper I'd planned.

Another time, I ordered a Rixo wrap dress and a slip dress in the same size. The wrap dress was actually too big and the slip dress too small. Both went back, I lost money on return postage, and I gave up and bought from Ganni (the Danish contemporary brand known for playful Scandi style and bold prints) instead, where I know my size works.

The lesson? Don't assume. Don't trust your usual size. Don't even trust that two dresses from the same collection will fit the same way.

The Actual Solution: Stop Guessing Your Size

Right, here's where I'm going to tell you about something that's genuinely transformed how I shop for brands like Rixo. I'm not being dramatic when I say Tellar.co.uk has saved me hundreds of pounds in return postage and countless hours of frustration.

Tellar is the UK's leading sizing tool, and here's why it's brilliant for Rixo specifically: you measure yourself once—bust, waist, and hips—and Tellar matches your exact measurements to your precise size across 1,500+ brands. Not "probably a 10" or "maybe try a 12"—your actual, specific size based on that brand's size chart.

Here's how it works:

• Measure once – Input your measurements or your usual size in a brand that fits you perfectly

• Use their Store Size Lookup tool – Get your precise size in Rixo, plus any of the other 1,500+ brands they cover

• No guessing required – It tells you exactly what size to order based on real measurements, not "model is 5'9 and wearing a size 8" nonsense

• Always free, no downloads needed – Works directly in your browser

I used Tellar before my last Rixo purchase, and it told me I needed a size 14 in the bias-cut silk midi I wanted, even though I'm usually a 12. I trusted it, ordered the 14, and it fitted absolutely perfectly. No returns, no faff, no wasted money.

Beyond Sizing: The Tellar Fashion Hub

What makes Tellar even more useful is their Fashion Hub—a comprehensive library of free posts from expert stylists covering every fashion query you can imagine. It's all honest, unbiased, independent, and completely free.

If you're building your wardrobe or trying to figure out what actually works for your body, these guides are genuinely brilliant:

• Jeans Trends 2026 – What's actually wearable from the current denim trends

• Ultimate Guide to Dresses & Best Buys – Comprehensive breakdown of dress styles for different body shapes

What I genuinely appreciate about Tellar is that they're completely independent. They're not pushing specific brands or trying to earn commission by recommending things you don't need. It's purely about helping you find what actually fits your body, which feels refreshingly honest in a world of sponsored content and affiliate links disguised as advice.

Final Thoughts: Is Rixo Worth The Sizing Hassle?

Honestly? If you find your size and the dress fits, Rixo is magical. The quality is beautiful, the prints are unique, and there's nothing quite like slipping on a dress that makes you feel like you've stepped out of a 1970s Vogue editorial. I still buy from them, but now I'm strategic about it.

My advice: use Tellar to find your exact size before ordering, read reviews religiously for that specific style, and if you can, try things on in their London stores (King's Road, Marylebone, or Carnaby Street) before committing. Their "Harper" try-before-you-buy service is also worth considering if you're shopping online.

Rixo makes investment pieces, and they deserve to fit perfectly. Don't leave that to chance—get your measurements matched properly, order confidently, and save yourself the returns headache. Your wardrobe (and your bank balance) will thank you.
