What Is Sizing Like at Bailey Rose?

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

Bailey Rose runs small — and if you're ordering from the UK without knowing that, you're in for a frustrating surprise. I've seen it happen more times than I care to admit: someone spots a gorgeous ruched midi or a sweet floral co-ord on ASOS, clicks buy in their usual UK 12, and it arrives clinging for dear life. The brand follows US junior sizing principles, which trend noticeably smaller than the standard UK high street fit. So before you add anything to your basket, let me save you the return postage.

So, Who Is Bailey Rose?

Bailey Rose is a Los Angeles-based womenswear brand that's all about that effortless California summer energy — think pastel palettes, milkmaid blouses, ruched bodycons, flirty A-line minis, and cute co-ord sets. It's very much designed for the girl who mixes vintage charm with modern trends and isn't afraid to be a bit playful with her wardrobe. You'll find it stocked on ASOS, through various US wholesale channels, and at Target in the States.

The price point is genuinely affordable — this is fast-fashion territory — and the aesthetic is undeniably fun. But with that comes a sizing reality check that UK shoppers particularly need to be aware of.

How Does Bailey Rose Sizing Work?

The golden rule: size up at least one, and sometimes two sizes from your usual UK fit. The brand labels its pieces in XS through XXL using US sizing conventions, and those sizes map to smaller measurements than you'd expect from the likes of M&S or Next.

Here's what I've noticed broken down by category:

Tops and crop blouses: These are where the sizing is most deceptive. Smocked or ruched styles especially — they may look stretchy but the overall cut runs narrow through the bust and shoulders. If you're a UK 12 upwards, definitely size up here.
Dresses: Bailey Rose dresses lean into short, structured shapes — A-line minis, ruched bodycons, milkmaid cuts. For relaxed styles with elasticated details, your regular UK size with one up should work. For anything structured or satin-finish, go by your bust measurement and err larger.
Bottoms (trousers and skirts): The brand loves a high waistline with a cropped or shorter leg. Waistbands run slightly snug, particularly in woven fabrics without stretch. If you carry more of your weight on your hips and thighs, I'd always go up a size — the waist-to-hip ratio on these pieces isn't especially generous.

My Honest Take on the Fit

I have a complicated relationship with fast-fashion sizing, and Bailey Rose is a prime example of why. I genuinely love the aesthetic — the ice cream-print maxis, the lace-trim satin dresses, the whole vibe. But the inconsistency between categories is real. I've tried pieces from this brand where the top half of a co-ord ran two sizes smaller than the bottom half. Not ideal when you're ordering online and can't try before you buy.

My advice? If you're buying a co-ord set and you're in between sizes — buy a size up on both, always. You can have the top taken in far more easily than you can unpick a too-tight waistband. And always, always check your measurements before ordering rather than going by the label. Honestly, this is where a decent sizing tool changes everything (more on that shortly).

What's the Fabric Like and Does That Affect Fit?

Bailey Rose works largely with lightweight polyester, cotton blends, and stretch satin — all fast-fashion staples. The plus side is that many of the pieces have a bit of give, which does help with fit. Elasticated bodices and smocked waistbands offer more flexibility than a structured woven will. The downside is that the fabrics aren't especially forgiving at the seams — if you're straining across the bust or hips, you'll see it. Go up a size and let the piece hang properly; it'll look infinitely better.

Alternatives to Bailey Rose — Similar Aesthetic, More Reliable Sizing

If you love the Bailey Rose look but want something that fits more predictably for a UK body, here are my picks at every budget level:

🛍 HIGH STREET PICKS

ASOS — Stocks Bailey Rose itself, but ASOS's own-brand ranges nail the same youthful, trend-led aesthetic with clearer UK sizing. Their curve and tall ranges are genuinely excellent too.
Urban Outfitters — The closest vibe match to Bailey Rose on the UK high street. LA-inspired prints, boho-adjacent silhouettes, and loads of co-ords. Sizing is more consistent and helpfully detailed.
Zara — If you want the ruched mini or satin midi look done with slightly more elevated fabric, Zara delivers consistently. Size guide is reliable once you know your measurements.
Mango — Beautiful pastel-toned dresses and co-ords with a more Mediterranean take on the same feminine aesthetic. Slightly more generous in the cut than Bailey Rose.
River Island — Brilliant for trend-led going-out dresses and playful prints. Good size range and generally honest sizing. I always recommend going by their cm measurements rather than just the number.
Abercrombie & Fitch — Has completely reinvented itself and now does gorgeous feminine dresses, mini skirts, and co-ords that scratch exactly the same itch as Bailey Rose. Sizing is very well documented.
Hollister — California-born like Bailey Rose, and the vibe is genuinely similar — relaxed, youthful, sun-kissed. Great for casual dresses and easy-wear tops at a very accessible price point.
Topshop — A classic for a reason. The trend-led dresses and co-ords on Topshop (now online via ASOS) are consistently well-fitting and cover a broad size range.

✨ PREMIUM PICKS

Free People — For the boho-romantic customer who loves Bailey Rose's milkmaid and floral aesthetic but wants better fabric quality and more considered construction. Sizing runs true to a US standard, so check measurements carefully.
Reformation — Elevated feminine dresses with a sustainability angle. If you're graduating from the Bailey Rose aesthetic into something more investment-worthy, Reformation is the natural next step.

💎 LUXURY / DESIGNER PICKS

Zimmermann — The ultimate expression of that sun-soaked feminine print dress energy, done in the most beautiful fabrics. A world away in price, but the aesthetic DNA is unmistakably related. Sizing runs small, so use measurements.
Faithfull the Brand — A premium Australian brand with a similar pastel palette and vintage-inspired silhouette. Think Bailey Rose all grown up. Sizing is consistent but lean.

Two Independent Brands Worth Knowing

Rouje — A French indie label that does the flirty floral dress better than almost anyone. The cuts are designed around a feminine silhouette and the quality is genuinely lovely. More of an investment, but pieces last seasons rather than weeks.
Fanfare Label — A UK-based sustainable womenswear indie that does vibrant prints, floaty silhouettes, and bold colour in a way that feels genuinely fresh. Great for the customer who loves Bailey Rose's playfulness but wants something more ethically made.
