What Is Sizing Like at Tribeca Atelier?

Tribeca Atelier doesn’t run on a conventional size chart — it’s a small-batch, made-to-order and one-of-a-kind atelier, which means “sizing’” here is all about each garment’s own measurements rather than reaching for a familiar S, M or L off a rail. If you’ve come here expecting a tidy little grid of UK numbers, I’m going to gently disappoint you — and then explain why that’s actually good news. As a stylist, the brands that make me work the hardest are nearly always the ones worth the effort, and this is one of them.

So how does sizing actually work here?

The atelier hand-makes its pieces in Tribeca from existing textiles — antique, vintage, deadstock and end-of-run cloth — cutting from their own patterns and finishing with hand-stitched details. Collections drop in tiny monthly batches, split between made-to-order and genuine one-of-a-kind pieces. Because every garment starts from a different bolt of cloth, the fit logic is completely different to the high street:

There’s no universal size run. One jacket might sit like a UK 10, the next like a generous 14, even with the same label inside.
Measurements beat labels every time. Each piece is described by its actual bust, waist and length in centimetres or inches — that’s the number you trust, not the size tag.
Made-to-order pieces flex to you. Hemlines, collar size, closures and proportion are adjusted per garment, so you’re part of the fit conversation.
One-of-a-kind means one chance. If a piece fits, buy it — it won’t be restocked in your size, because there is no “your size” in the mass-market sense.

My honest stylist take on the fit

Atelier pieces like these tend to wear roomier and more sculptural than you expect, because they’re designed around the cloth rather than a slim commercial block. I learned this the hard way years ago with a hand-made deadstock coat I bought purely on the photo — I assumed “my size” and it swam on me at the shoulder. Lesson burned in: with makers like this, I now measure a garment I already own and love, then compare it line for line. My win came the second time round — a structured jacket I measured properly that became the most-complimented thing I own. Get a tape measure out, note your favourite blazer’s shoulder, bust and length, and shop against those numbers.

Where to shop if you love the look but want reliable sizing

If the structured, hand-finished, considered feel is what pulls you in but you want a dependable size guide to shop with, here’s where I’d send clients across three price tiers.

High street

Whistles — clean, directional tailoring with a quietly modern hand; their blazers nail that atelier silhouette and run pleasingly true to size.
Jigsaw — beautifully cut, fabric-led staples; a brand that thinks like a maker rather than a trend-chaser, with a generous, forgiving fit.
Massimo Dutti — elevated tailoring with a genuine atelier sensibility at high-street prices; sizing leans slim, so size up on anything structured.
Reiss — precise, architectural tailoring and sharp shoulders; runs true but cut for a leaner frame through the waist.
Me&Em — clever proportion play and considered design, with some of the most reliable, true-to-size fit on the high street.
Hush — relaxed but considered everyday pieces in lovely natural cloth; a roomy, easy fit that suits the lived-in atelier mood.
Mint Velvet — soft, textural, contemporary separates with a slightly slouchy line; generous sizing, ideal for layering.

Premium

Sézane — the Parisian label with that effortless, slightly artisanal hand; fit runs petite, so size up if you’re between.
Toast — the closest mainstream match to the atelier ethos: natural fibres, craft detailing and roomy, intentional cuts.
By Malene Birger — sculptural, statement Scandi tailoring with real drama; sizing is true but designed with volume in mind.

Luxury & designer

Totême — quietly luxurious, architectural minimalism; investment pieces with clean, true-to-size proportions that last decades.
Max Mara — the coat house, all structure and craftsmanship; tailoring runs slightly generous, so trust your usual size.

Two left-field independents worth knowing

Lowie — a small London slow-fashion label working in natural, often hand-loomed fabrics; characterful, generously cut and made to be kept.
Beaumont Organic — UK ethical maker producing in small runs with a considered, relaxed fit; the kind of indie that shares the atelier’s values without the lottery on sizing.

The bottom line

Tribeca Atelier isn’t a brand you “know your size” in — and that’s the whole point. You’re buying a one-off, so you shop by measurements and a bit of instinct, not a label. Treat each piece as its own conversation, measure twice, and you’ll end up with something nobody else owns.
