What Is Sizing Like at Wyse London? A Stylist's Honest Fit Guide

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

Wyse London runs true to size overall, but uses its own numbered sizing system (Wyse 0 to Wyse 6, covering UK 6 to UK 18), and there are a few garment-specific quirks worth knowing before you click buy — particularly with their knitwear, which is the heart of the brand.

I've been a fan of Wyse for years. There's something genuinely joyful about the brand — the prints, the colour, the way a Wyse knit can make a Tuesday feel like a occasion. But I'll admit, the first time I ordered, I stared at the size chart for a good few minutes wondering what on earth a "Wyse 2" was. Once you crack the code, it's straightforward. Let me save you the confusion.

Understanding Wyse London's Sizing System

Unlike most brands that use standard UK 8–18 or XS–XL labels, Wyse has its own sizing scale. It runs from Wyse 0 (UK 6) through to Wyse 6 (UK 18). Their size guide uses bust, waist, and low hip measurements, so do have a tape measure to hand before ordering. It sounds fiddly, but once you've found your Wyse number, it stays consistent across most of their collections.

Always measure bust, waist, and low hip (approx. 20cm below your natural waist) for the most accurate Wyse size. If you fall between two sizes, Wyse recommend going with your bust measurement as the priority.

Does Wyse London Run True to Size?

Mostly, yes — but with a few caveats depending on the garment category. Here's the honest breakdown from customer feedback and my own experience ordering from them:

Knitwear: This is where it gets interesting. Wyse's knits are beautifully made with heavier fabrics, and the weight of the yarn can mean the fit is slightly snug across the bust. If you have a fuller bust, I'd strongly recommend sizing up. I made the mistake of sticking with my usual size on a chunky ribbed jumper and spent the whole evening tugging it down. Lesson learned.
Dresses: Generally true to size, with a high, defined waist that's especially flattering if you're petite or have a shorter torso. Customer reviews consistently praise the waistline placement — it hits in exactly the right spot.
Trousers & jeans: True to size in the leg, but some customers at a UK 14 find the waistband slightly snug. If you're between sizes, go up in the waist and belt it down if needed.
Blouses & tops: True to size, with a slightly relaxed cut through the body. If you prefer a more fitted look, consider sizing down. For a billowy, worn-in feel (very much the Wyse aesthetic), your usual size will be perfect.
Dungarees: Wyse's iconic scallop dungarees have a relaxed fit with a little stretch, and they come up as expected for most body shapes. Tall women should note the leg length is standard — if you're 5'10" or above, they'll skim the ankle exactly as intended.

The Wyse Aesthetic — And Who It's Really For

Wyse was launched in 2014 by Marielle Wyse on a mission to find knitwear that wasn't "lacking in joy" — and honestly, she's delivered on that brief spectacularly. The brand has built a devoted following of women who've grown out of fast fashion and want to invest in pieces that feel both elevated and wearable. Think rich autumnal tones, punchy prints, broderie-trimmed blouses, and those now-famous dungarees. It's joyful, considered dressing without taking itself too seriously.

The size range covers UK 4–18 (Wyse 0–6), which is broader than many premium independents. Prices sit between roughly £60 and £395, so this is a "save and splurge" brand rather than an everyday impulse buy — but the quality absolutely backs up the price point.

If Wyse Doesn't Quite Fit, Here's What Else to Try

Wyse occupies a lovely niche — premium, playful, and very British in spirit. If the sizing isn't working for you, or you want to build out a wardrobe in the same spirit at different price points, here's where I'd send my clients:

High Street & Accessible Brands:

Boden — The closest high street equivalent in terms of print-led, joyful dressing. Sizing is consistent and generous, with excellent petite and tall options.
White Stuff — Brilliant for textured knitwear and relaxed separates with character. Runs true to size, slightly generous through the body.
Anthropologie — A brilliant match for Wyse's love of print and detail. Sizing can vary by brand carried but their own-label pieces are generally true to size.
Mint Velvet — A go-to for elevated everyday dressing. Well-cut knitwear and relaxed trousers that sit in a similar style register to Wyse at slightly lower price points.
Jigsaw — For women who want understated British craftsmanship. Sizing is true-to-size with a slightly longer hem, which is brilliant for taller women.
Phase Eight — Especially strong on occasion dressing and print. Sizes consistently true and has a brilliant fit in dresses for curvier figures.
Hobbs — Classic tailoring done beautifully. If you love the Wyse aesthetic but need something smarter, Hobbs delivers on quality at a comparable price point.
Whistles — Pared back but characterful. Their blouses and knitwear are excellent quality and size consistently well across the range.

Independent Picks You Might Not Know (But Should):

Baukjen — A genuinely wonderful independent British brand with a strong sustainability story. The knitwear and jersey pieces are beautifully cut and size true to UK sizing. Very similar customer base to Wyse.
Cefinn — Founded by Samantha Cameron, Cefinn makes elevated, print-forward pieces in a very similar spirit to Wyse. Sizing is consistent and the quality per pound is excellent.

Premium & Designer Options:

ME+EM — The premium step up from Wyse. Impeccably made, true to size, and built to last. Their knits in particular are exceptional.
Totême — For those who want to dial up the quiet luxury angle. Minimal, beautifully cut, and consistent sizing across the board.
The Row — If budget isn't a concern, The Row represents the pinnacle of understated, considered dressing. Sizing is precise — measure carefully.
