What is Sizing Like at Extro & Vert?

Extro & Vert is a UK-based luxury ready-to-wear brand founded in 2020, offering sizes from UK 6 to UK 16 with a general true-to-size fit across its tailored co-ord sets, dresses, and blazers.

I'll be completely honest — when I first came across Extro & Vert, I thought it was just another Instagram-pretty brand that would look incredible on a hanger and disappointing in person. You know the type. I'd been burned a few too many times by that particular fashion trap. But I gave it a chance, ordered a blazer co-ord set in my usual size 10, and I am so glad I did. The fit was genuinely impeccable — structured without being stiff, polished without being stuffy. It's become one of those pieces I reach for whenever I need to look like I actually have my life together.

So if you've been circling Extro & Vert on ASOS or their own website, wondering whether to trust the sizing, let me walk you through everything you need to know before you buy. I want you to have the same happy unboxing moment I did — not the disappointing one.

So, Does Extro & Vert Come Up True to Size?

Yes — across the majority of their range, Extro & Vert is true to size. Their own size guide states this clearly, and from personal experience and customer feedback, it holds up. If you're typically a UK 10, go for a UK 10. You don't need to size up or down as a rule.

That said, there are a few things worth keeping in mind:

The tailored pieces — think blazers, structured trousers, and co-ord sets — tend to be cut close to the body. If you're between sizes or carry weight in your shoulders, sizing up one can give you a slightly more comfortable fit without losing the sharp silhouette.
Dresses and jumpsuits are generally more forgiving. I'd stick with your usual size here.
Cup-size considerations — this is something I genuinely appreciate about Extro & Vert. Some styles are designed with bust shaping in mind, and the brand incorporates cup sizing into certain garments, which is a thoughtful touch you don't always see at this price point.
Check the individual product page — Extro & Vert advises this for good reason. Lengths and specific measurements do vary by style, so a quick look at the product-level size guide is always worth it before checking out.

How Does It Compare to High Street Sizing?

This is where it gets interesting. Extro & Vert sits in that sweet spot between premium and accessible luxury — it's not high street, but it's a useful reference point to know how it aligns with the brands you probably shop most often.

Zara — Extro & Vert runs similarly to Zara's tailored range. If you're a Zara 10 in their blazer section, you'll likely be the same at Extro & Vert.
ASOS — ASOS own-brand sizing can be a bit inconsistent, but Extro & Vert (which stocks on ASOS) tends to be more consistent. Go by measurements rather than ASOS's general sizing guide.
H&M — H&M often runs slightly larger in tailored pieces. You may find your usual H&M size is a touch roomy at Extro & Vert — consider your measurements rather than your H&M label alone.
Mango — A great reference point. Extro & Vert and Mango sit in a similar fit territory for structured pieces. True to size in both.
River Island — River Island tailoring can run a little small in the body. Extro & Vert's blazer cut is comparably fitted, so if you go up at River Island, you may want to do the same here.
Topshop — The legacy Topshop sizing (now mainly online via ASOS) ran consistently, and Extro & Vert aligns fairly closely with it. Like-for-like sizing tends to work well.
Marks & Spencer — M&S typically cuts with a little more ease. If you wear an M&S 12 for comfort, you may want to size down to a 10 at Extro & Vert depending on your preference for fit.
Next — Next sizing is generally generous and true to size. Extro & Vert is similarly reliable, though the fit is more tailored through the body than Next's standard cuts.

What's the Fit Actually Like?

The brand describes its aesthetic as "timeless, modern, and refined" — and honestly, that translates directly into how the clothes sit on the body. This is not a slouchy, relaxed-fit kind of brand. Extro & Vert is built for a clean, polished silhouette. Blazers are fitted through the shoulder and waist. Trousers are tailored with high waists and structured falls. Dresses tend to be body-conscious but not restrictive.

I'd describe it as the kind of brand that makes you stand up a little straighter the moment you put it on. There's something about a well-cut co-ord that just does that to you — I learned that lesson the hard way after years of thinking that only designer pieces could deliver that feeling. Extro & Vert proves otherwise.

The fabrics reinforce this. There's real weight and quality to the garments — not that cheap, flimsy feel you sometimes get with Instagram-adjacent brands. Think structured blazer fabric, smooth tailored trousers, and considered drape on their dresses.

My Two Independent Brand Picks to Wear Alongside Extro & Vert

If you love the Extro & Vert vibe and want to build out your wardrobe with similar energy, here are two independent picks I'd point you towards:

Nadine Merabi

If Extro & Vert is your daytime power look, Nadine Merabi is its evening counterpart. This Manchester-based luxury brand makes the kind of sequin and embellished occasionwear that genuinely stops people in their tracks. Sizing is consistent and true to size — order your usual. The quality is exceptional for the price point, and the attention to fit rivals far more expensive designer pieces. I wore a Nadine Merabi sequin suit to a work event once and received more compliments than I have in my entire fashion career. Not an exaggeration.

Rixo

For a contrast to Extro & Vert's tailored aesthetic, Rixo brings beautiful print, femininity, and a relaxed yet elevated feel. Rixo tends to run true to size with a slightly generous cut in their dresses, so stick with your usual. The two brands complement each other perfectly if you're building a wardrobe that takes you from the boardroom to a garden party without skipping a beat — which, frankly, is exactly the kind of wardrobe I aspire to have at all times.
