What Is My Size at In Wear?

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

In Wear runs true to its European sizing, which typically sits one size larger than standard UK sizing — so if you're a UK 10, you'll almost certainly be reaching for an In Wear 36, and a UK 12 translates to an In Wear 38. It's a consistent system once you get your head around it, but it trips up a surprising number of women (myself included, the first time I ordered online and ended up with a blazer I could have shared with my flatmate).

Getting to Know In Wear

In Wear is a Danish womenswear brand with serious Scandinavian credentials — clean lines, considered tailoring, and that effortlessly polished aesthetic that the Danes do so brilliantly. It sits in a lovely sweet spot between smart high street and premium designer, which is exactly why it attracts women who want quality without the full luxury price tag. The brand is part of the IC Companys stable (alongside Matinique, Part Two and others), and it shows in the consistent fit philosophy: structured, slightly fitted, and designed with a grown-up wardrobe in mind.

The clothes are beautifully made. Tailored trousers, sleek knitwear, relaxed-but-polished blouses — this is a brand for women who've moved beyond the trend treadmill and want pieces that genuinely work. But that tailored cut means fit really matters here, and getting your size right is half the battle.

How In Wear Sizing Actually Works

In Wear uses European sizing throughout — so you'll see labels like 34, 36, 38, 40, 42 rather than UK 8, 10, 12, 14, 16. The general rule is to add two to your UK size to get your In Wear size. But here's where I'd urge you not to stop there, because the cut matters enormously depending on the garment.

Tailored pieces (blazers, trousers, structured skirts): These tend to cut close through the shoulder and hip. If you're between sizes or carry more volume through the hips, size up — it's much easier to have a waist taken in than to wrestle with a jacket that pulls across the back.
Knitwear & relaxed tops: These are generously cut and true-to-size. The brand's knitwear in particular has lovely ease built in, so go with your standard European equivalent and you'll be fine.
Dresses: In Wear dresses often have a defined waist, so be led by your largest measurement — typically hips — and adjust from there. I'd always recommend checking the specific measurements in their product listings rather than relying solely on the size label.
Trousers: Fit well through the thigh on a straighter figure but can feel snug if you're curvier through the hips and thighs. Again, sizing up and having the waist adjusted is a worthwhile investment for a pair of trousers this good.

My Honest Experience With In Wear Fit

I'll be straight with you — I had a bit of a learning curve with In Wear. I ordered a pair of their wide-leg tailored trousers in my usual European equivalent and they were perfect through the hip but slightly loose at the waist. The solution? A simple tuck from a local tailor that cost less than a tenner and transformed them into some of the most-worn trousers in my wardrobe. That's the thing about quality tailoring — it's worth the minor adjustment.

I've also noticed that In Wear's blazers can run slightly narrow across the shoulders if you have broader shoulders, so if that's you, definitely try before you buy or check the brand's shoulder measurement data before ordering online.

Who Is In Wear's Sizing Designed For?

In Wear's core sizing range runs from EU 32 to EU 46 (roughly UK 6 to UK 18), though availability varies by style. The brand's aesthetic and cut leans towards a more linear, Scandinavian silhouette — which means it's often most flattering on straighter body shapes. That said, their looser knits, wrap styles and flared trousers are genuinely brilliant for hourglass and pear shapes too. It's about picking the right styles for you, rather than the brand being off-limits to anyone.

High Street Alternatives to Shop Alongside In Wear

If you love the In Wear aesthetic — that clean, Scandi-inflected tailoring — these high street and premium brands offer a similar sensibility and are worth having on your radar:

Whistles — consistently one of the best for polished, workwear-adjacent tailoring on the UK high street. The sizing is straightforward UK and the quality punches well above the price point.
Jigsaw — a perennial favourite for clean-lined, seasonless pieces. Very similar customer in terms of aesthetic and age range to In Wear, and the sizing is reliable.
Massimo Dutti — part of the Inditex family but miles ahead of its siblings in terms of quality. The tailoring is excellent and the minimalist palette overlaps strongly with In Wear.
Reiss — slightly more fashion-forward than In Wear but shares that premium feel. Great for blazers and dresses if you want something a touch more occasion-ready.
Me&Em — a brilliant British brand for elevated basics. The quality is genuinely impressive and the brand is especially strong on knitwear and classic trousers.
Phase Eight — underrated for tailoring. Strong on dresses and occasionwear, with a relaxed approach to sizing that tends to be forgiving across the range.
Hobbs — long trusted for smart, structured pieces with a very consistent fit. If you find In Wear's European sizing a headache, Hobbs offers a reliable UK-size alternative with a similar grown-up sensibility.
Cos — the Scandi aesthetic crossover is obvious here. Cos shares In Wear's love of architectural silhouettes and runs with European sizing too, so once you know your In Wear size you'll likely find the same number works at Cos.

Independent Brands Worth Discovering

Two independent names I'd encourage you to explore if In Wear has you hooked on the Scandinavian aesthetic:

Stine Goya — a Copenhagen-based brand beloved by stylists and fashion editors alike. More colourful and print-driven than In Wear, but with that same quality of construction and a fit that tends to be relaxed and flattering. A genuine wardrobe cult brand.
Baum und Pferdgarten — another Danish label with a slightly more eclectic, artsy energy. Their tailoring is excellent, sizing runs consistently European, and they're a brilliant discovery if you want In Wear's quality with a bit more personality.

Luxury & Designer Alternatives

If In Wear sits at the premium end of your budget and you're considering an upgrade, the Scandinavian design houses worth looking at include Toteme (minimalism at its most refined), Acne Studios for those who love clean tailoring with a slight edge, and By Malene Birger — another IC Companys brand, as it happens, with a slightly more luxurious feel and price tag to match.
