What Is Sizing Like at Thom Krom? Your Complete Fit Guide

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

Thom Krom runs large — particularly in tops, sweatshirts and outerwear — so as a general rule, size down one from your usual UK size, especially if you want a sharper, more structured silhouette. Bottoms and base layers tend to sit truer to size, depending on the cut and stretch content of the fabric.

I'll be honest — the first time I ordered from Thom Krom I completely misjudged it. I bought a sweatshirt in my regular size and it arrived looking like I'd borrowed it from someone considerably bigger. Not in a chic, intentional-oversized way. In a drowning way. Lesson learnt. Once I sized down and understood the brand's design logic, everything clicked — and I've been obsessed ever since.

What Is Thom Krom?

If you haven't come across Thom Krom before, you're in for a treat — or a bit of a rabbit hole, depending on your budget. Founded in 2009 by German fashion scout Thomas Kromik, it's a Berlin-born label built entirely around a monochrome, avant-garde aesthetic. Think raw edges, drop shoulders, deconstructed silhouettes, and technical fabrics with real intention behind them. The women's collection is designed by Ramona Ramsel, and it has its own identity — still deeply architectural, still rooted in that dark urban energy, but with a more fluid, feminine sensibility woven through.

It's the kind of brand that fashion editors reach for when they want something that doesn't look like anything else in the room. Not flashy. Not logo-driven. Just quietly, confidently different.

How Does Thom Krom Sizing Work?

Thom Krom uses standard international sizing (XS through XL) but the fit varies noticeably across garment types. Here's what you need to know before you buy:

Tops & sweatshirts — These run large, often intentionally so. The drop-shoulder construction and relaxed cut mean your usual size will give a very oversized result. Size down one for a contemporary relaxed fit, or two if you want something more fitted.
Outerwear & jackets — Also on the generous side. Their quilted and padded coats in particular are designed with an oversized profile. If you're layering underneath, your regular size works. For a cleaner line, go a size down.
Trousers & bottoms — These are far more accurate. Low-crotch styles and jogger silhouettes in stretch fabrics tend to run true to size. Their tailored trousers and wide-legs are also fairly reliable — stick to your regular size here.
Base layers & fitted jersey — T-shirts, bodysuits and ribbed knits in stretch cotton or viscose blends run true to size, sometimes even a touch small. Don't size down on these.
Dresses & jumpsuits — It depends entirely on the silhouette. A wide-leg jumpsuit with adjustable straps? Size up if in doubt. A fitted sheath? True to size or one down.

Fabrics & Why They Affect Fit

One thing that genuinely sets Thom Krom apart — and affects fit in a real way — is the quality and variety of its fabrics. They use Japanese cotton blends, raw-edge jersey, washed and cold-dyed finishes, linen-cotton mixes, technical stretch nylons, and waffle-texture piqué. Each behaves differently on the body:

Japanese cotton blends — Dense, slightly stiff initially, but they soften beautifully with wear. These hold their shape well so sizing down works cleanly.
Stretch jersey & cotton-elastane mixes — Far more forgiving. True to size, flattering, and comfortable. These are the pieces that feel wearable every day.
Linen-cotton blends — The linen pieces (and they do beautiful linen shirting and dresses) have a natural drape and breathability. They're often deliberately oversized in cut, so follow the size-down guidance.
Technical nylon outerwear — Their padded and puffer styles use water-repellent nylon shells. These are structured and roomy — true to size if layering, size down for a sleeker silhouette.

How to Style Thom Krom

The brand's whole identity is built around layering within a monochrome palette, and once you get that, dressing in it becomes almost effortless. My own approach when styling clients in Thom Krom:

Pair an oversized sweatshirt or raw-edge tee with their tapered or barrel-leg trousers — the volume contrast is the whole point.
Layer a quilted puffer vest over a fine-knit crewneck and slim trousers. The proportions are everything.
Use their linen shirt-dresses as layering pieces over a fitted body — worn open with wide-leg trousers, it's one of those looks that takes five minutes and looks intentional for hours.
Stick to black, off-white, and charcoal. The brand's whole palette is deliberately narrow, and that's where it sings.

Where to Buy Thom Krom in the UK

In the UK, Thom Krom is available through a handful of specialist stockists rather than mainstream department stores. Collard Manson (collardmanson.co.uk) is probably the best UK-based destination — they stock a solid women's edit and are reliable for sizing information. You'll also find it on Farfetch and YOOX, both of which have good ranges and useful size filter tools. For European stockists with worldwide shipping, INN7 and Jades24 are worth knowing.

Similar Brands — Because Not Everyone Can Drop €200 on a T-Shirt

Thom Krom sits at a premium-to-designer price point, so here are my honest recommendations across different budgets if you love the aesthetic but need options:

High Street Picks

All Saints — The closest high street match for that dark, urban, raw-edge energy. Their leather pieces and draped jersey basics are genuinely excellent for the price.
COS — Architectural cuts, muted tones, and strong fabric stories. Their oversized coats and structured knitwear have real design credibility.
Whistles — More understated than Thom Krom but shares the commitment to clean lines and quality finishing. Good for layering basics.
Massimo Dutti — Quietly excellent tailoring in a similar monochrome palette. Their tailored trousers and outerwear are a strong affordable alternative.
Me&Em — Superb quality for the high street, particularly for jerseys and knits in muted tones. Not edgy exactly, but the fabric quality rivals brands costing twice as much.
Urban Outfitters — For the younger end of this aesthetic — oversized, deconstructed basics, and a genuinely curated monochrome edit at accessible prices.
Reiss — For occasions when you need the Thom Krom look but in something a boss can't raise an eyebrow at. Their tailored suits and outerwear do this well.
Mango — Consistently delivers minimalist, well-cut pieces in neutral palettes. Their linen and washed-cotton ranges have quietly become underrated.

Premium Picks

Isabel Marant — Not monochrome in the same way, but shares that Parisian-meets-underground design sensibility. The quality and fabric innovation are comparable.
Rick Owens (diffusion lines) — If you're flirting with the Thom Krom aesthetic and want to go deeper, Rick Owens' DRKSHDW line is the next step up in raw, architectural darkness.

Independent / Niche Picks

Hannes Roether — A German label with an almost identical design DNA to Thom Krom: muted tones, quality jerseys, dropped shoulders, and a strong emphasis on texture. Genuinely underrated and absolutely worth discovering.
Baserange — A Copenhagen-based label doing beautiful, minimal knitwear and jersey basics in a strictly muted palette. Sustainable production, exceptional fabric quality, and the kind of quiet confidence that pairs perfectly with bolder Thom Krom pieces.
