What Is Sizing Like at Yumi? Your Complete Fit Guide

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

Yumi sizing is broadly true to size following standard UK sizing from 8 to 20, but their dresses and tops can run slightly small — particularly in non-stretch fabrics — so if you're sitting between two sizes, I'd always recommend going up rather than down.

I've been a Yumi fan for years. There's something genuinely joyful about the brand — vibrant prints, feminine silhouettes, that Camden-market-meets-cocktail-party energy that not many labels can pull off. But I'll be honest: the first time I ordered one of their wrap dresses, I confidently went for my usual size 12 and spent the next five minutes hopping around my flat trying to pull it over my hips. Lesson learned. Once I sized up, it was perfect — and I've worn it to death.

Here's everything you need to know before you order.

Measurements are body measurements, not garment measurements. If you're between sizes, size up.

How Does Yumi Sizing Vary by Garment?

Not all Yumi pieces fit the same way — and this is where a lot of people come unstuck. Here's a quick breakdown by category:

Dresses: This is where the slightly-snug issue shows up most. Wrap styles and bodycon midi dresses in particular run small through the bust and hips. I'd say size up if you're a fuller bust or carry weight on your hips. Jersey and stretch-fabric dresses are far more forgiving — your usual size should work fine.
Tops & blouses: Generally true to size, but printed satin and woven styles can be fitted through the shoulders. If you have broader shoulders, order up.
Jumpsuits: This is where Yumi's customers have the most mixed experiences. A minority report them running small through the torso. If you're longer in the body, go up a size for comfort.
Skirts: Tend to be more relaxed and consistent — true to size in the majority of cases. Floaty tiered styles especially are very size-friendly.
Knitwear & gilets: Some reviewers have found these run slightly large. Going with your usual size is fine; if anything, some pieces have been noted as generous.
Occasionwear & evening tops: True to size for the most part — Yumi's sparkly and lace occasion tops get consistently good fit feedback from customers.

What Yumi Customers Actually Say About the Fit

I always dig into real customer reviews before I write one of these guides — no point in just regurgitating the official size chart. The consensus on Yumi is pretty clear: when it works, it really works. Loads of customers rave about the fit being spot-on, particularly on dresses. But there's a thread running through the reviews about certain styles being a size smaller than expected — which aligns entirely with my own experience.

The fabric makes a real difference here. Yumi's jersey and stretch pieces are generally kind to the sizing process; their more structured, woven prints are the ones to watch. It's also worth noting that Yumi has occasionally had consistency issues across different batches — something a few loyal customers have flagged — so checking individual product reviews before purchasing is genuinely worthwhile.

Yumi Sizing Tips: My Honest Advice

Always measure your bust, waist and hips before ordering — don't just go from memory.
If you're between a 12 and 14, go for the 14 in Yumi. You can always belt it.
Check whether the fabric has stretch. If it says viscose or woven cotton with no elastane, size up.
Read the individual product reviews on the Yumi website — they're often very specific about fit.
Petite customers find Yumi dresses can run slightly long — bear that in mind if you're under 5'4".

Brands Similar to Yumi — And How Their Sizing Compares

If you love Yumi's aesthetic but want to branch out, or you're looking for alternatives with more predictable sizing, here are my honest picks across all budgets:

High Street & Mid-Range:

Monsoon — A natural go-to for anyone who loves Yumi's printed occasion dresses. Monsoon sizing is consistent and tends to be slightly more generous through the hips, which I find really helpful. Great for weddings and garden parties.
Phase Eight — More polished and structured than Yumi, but equally prints-forward for occasionwear. Phase Eight runs true to size with a slightly longer hemline, ideal if you're 5'6" and above.
Anthropologie — If you love Yumi's indie-boho energy, Anthropologie is the natural next step. Sizing tends to be true to size; their floral midi dresses are consistently reviewed as running accurately.
White Stuff — A brilliant option if you want that relaxed, feminine print aesthetic in more breathable natural fabrics. Sizing is generous and very consistent — a real breath of fresh air if Yumi's fit frustrates you.
Oliver Bonas — Underrated for occasion dresses and printed co-ords. True to size, well-cut through the waist, and the quality feels punchy for the price.
Boden — For the more colourful, print-obsessed customer, Boden offers brilliant sizing consistency. They even have a petite range. I always recommend Boden to clients who want the Yumi mood without the sizing lottery.
Ted Baker — More of a step up in price, but Ted Baker's fit is excellent across dresses and occasion tops. Note: Ted Baker uses its own numbered sizing (0–5), so check their conversion chart carefully.
Mint Velvet — Gorgeous for the grown-up, feminine customer. Mint Velvet sizing is reliable and slightly relaxed through the body — perfect if you find Yumi snug.
Coast — Still going strong for occasionwear. True to size, with flattering cuts through the waist. A solid alternative if you're dressing for an event and can't risk a sizing gamble.

Independent Labels Worth Knowing:

Ghost London (ghost.co.uk) — If you're a Yumi lover, Ghost should absolutely be on your radar. Their bias-cut, silky dresses are genuinely beautiful, and the slinky stretch fabric means sizing is very forgiving. A more elevated, understated take on the feminine print dress — and sizing is TTS with real ease of fit.
Collectif Clothing (collectif.co.uk) — For the vintage-inspired, print-obsessed customer who's slightly more rockabilly than boho. Collectif makes the most incredible 1950s-silhouette printed dresses, and their sizing is consistent and well-documented with detailed measurements per style.

Premium & Luxury Alternatives:

Rixo — The premium answer to Yumi's printed dress aesthetic. Rixo sizing runs true to size in most styles, but their silk pieces can feel fitted. Worth checking individual style reviews before ordering.
Ulla Johnson — For the luxury end, Ulla Johnson offers stunning printed and embroidered pieces. Sizing follows standard US/EU measurements; order using your measurements rather than label size.
Zimmermann — The ultimate luxury print brand. Be warned: Zimmermann runs small — sometimes by two full sizes — and is notorious for it. Always, always consult the size chart and go up.
