Does Izabel London Run True to Size? A Stylist's Honest Sizing Guide

By Ella Blake – fashion stylist | Tellar Fashion Hub – Always honest, unbiased & unsponsored

Yes – Izabel London generally runs true to size, but there are some real caveats worth knowing before you click 'buy'. The brand covers a wide range of styles, from floaty printed midi dresses to more structured woven occasionwear, and those two categories do not always behave the same way on the body. I've had both brilliant and baffling experiences with Izabel over the years, so let me save you the faff of unnecessary returns.

What Is Izabel London?

For anyone unfamiliar, Izabel London is an independent British womenswear label that's carved out a lovely niche in the mid-market space. Think feminine prints, relaxed silhouettes, wrap-style dresses, boho-inspired midi lengths, and surprisingly good occasionwear at a very reasonable price point. They also run a Curve range up to a UK 26, which is genuinely worth knowing – their inclusive sizing has improved considerably in recent years.

They're not a brand that screams from the shelves of your local high street, but they have a loyal following – and once you've found your size, you'll know why. The trick is finding that size in the first place.

How Does Izabel London Sizing Work?

Here's what I've observed both from personal experience and from a good deal of customer feedback:

Relaxed styles and jersey pieces – these are your safest bet. Wrap dresses, jersey midi dresses, and soft-knit pieces all tend to be true to size, sometimes even slightly generous. If anything, you might want to size down if you prefer a more defined look.
Fitted woven dresses and structured tops – this is where it gets trickier. Non-stretch fabrics, particularly around the bust and upper arm, can run a little snug. If you're fuller-busted or have broader shoulders, go up a size here without hesitation.
Occasionwear and lace styles – beautiful as they are, these often have the least give. I once bought a lace-trim shift dress in my usual size and could barely get it past my ribcage. Lesson learned: if it's a structured fabric, size up.
Stretch trousers and elasticated waist styles – genuinely forgiving. Stick to your usual size and you'll be fine.

One consistent grumble from customers is the bust-waist split: the waist fits perfectly, but the bust pulls. This is especially common in their tailored dresses and woven tunics. If this sounds like your shape, Tellar's sizing tool will actually map your measurements to the exact style so you know in advance – more on that below.

Izabel London vs. Similar Brands – Sizing Comparison

If you're a fan of Izabel, you probably also shop at brands with a similar aesthetic. Here's how their sizing stacks up against some of the most popular alternatives:

Phase Eight – slightly more structured than Izabel; runs true to size but tailored pieces can also pull across the bust. Both brands are fairly consistent with standard UK sizing.
Monsoon – very similar sizing to Izabel across their printed dress ranges. Monsoon's jersey pieces are equally forgiving, and their occasionwear tends to be cut slightly more generously.
Mint Velvet – a touch more polished and slightly more generous in cut. If Izabel feels snug in tailored styles, Mint Velvet often gives a bit more room in the right places.
Boden – similar relaxed British sensibility but with more consistent sizing across the range. Their printed midi dresses are an excellent alternative if you want that same boho-meets-smart feel.
White Stuff – another great comparison. White Stuff's jersey and linen pieces sit very similarly to Izabel's relaxed range; both brands are honest about sizing without much vanity sizing going on.
Coast – for the occasionwear category, Coast runs very slightly smaller than Izabel in structured styles. Worth sizing up if you're switching between the two for events.
Great Plains – often underrated, Great Plains runs true to size and sits at a comparable price point. Their jersey dresses are genuinely comparable to Izabel's best-sellers.
Oliver Bonas – a little more generous in cut than Izabel. If you find yourself sizing up in Izabel's woven pieces, Oliver Bonas is worth trying in your usual size first.

Two Independent Brands Worth Knowing

I always think it's worth going off-piste for a couple of recommendations – there are some brilliant independent labels doing similar things to Izabel, but flying a little more under the radar:

Yumi London – an independent British brand with a similar love of bold prints, floaty silhouettes and feminine details. Sizing is true to size and their fit is very consistent across the range. Their occasionwear is particularly good.
Joanie Clothing – a fantastic independent label with a retro-inspired print aesthetic that will appeal to Izabel fans. They're very clear about their sizing, run true to UK sizes, and have brilliant reviews for fit consistency. A real find.

My Best Tips for Getting Your Izabel London Size Right

Always check the fabric content before buying – if there's less than 4% elastane in a close-fitting style, size up.
Wrap dresses are almost always your safest bet and the most forgiving cut the brand does.
If you're between sizes, go up rather than down in woven or non-stretch pieces.
Their Curve range is genuinely worth exploring even if you're on the smaller end of plus-size – the cuts are flattering and the sizing is consistent.
Don't be put off by one bad fit experience. Their jersey and relaxed ranges are reliably true to size; it's only the more structured pieces that need a little care.

What's Actually Worth Buying at Izabel London?

In my experience, the brand's sweet spot is their printed midi and maxi dresses – lightweight, genuinely pretty, and at a price point that doesn't make you wince. Their knitwear is a solid seasonal buy too, though be aware that it can run slightly oversized depending on the style. For occasionwear, the lace-trim pieces photograph beautifully but do size up. And if you're looking for affordable holiday packing, their floaty tiered skirts and elasticated-waist trousers are brilliant and reliably sized.
