Lay something you already own flat and compare. That beats measuring yourself every time.

Length grows a long way across the range — 23" at XS to 32" at 2XL — so the larger sizes read noticeably longer, not just wider. The cuff opens from 3.5" flat to 8.25", which is the widest spread on the chart.

Lay something you already own flat and compare. That beats measuring yourself every time.

Length grows a long way across the range — 23" at XS to 32" at 2XL — so the larger sizes read noticeably longer, not just wider. The cuff opens from 3.5" flat to 8.25", which is the widest spread on the chart.

Our clothes are cut generously on purpose, so the number on the label matters less than the two or three measurements underneath it. Here's everything you need to find your size — and someone to email if you'd rather just ask.

Start with your body

The chart below is body measurements, so measure yourself and find the row you land in. Every product page carries that style's own flat measurements under Fit & feel — that's where you'll see how much room the garment actually adds.

Read this first. Many of our styles are designed relaxed, boxy or oversized, and they're meant to be worn that way. Two sizes can share a chest measurement and still feel completely different on. Check the fit note on the style you're looking at before you decide.

US size	Our size	Chest	Waist	Hips

12-14	XXXL	42–44"107–112 cm	35–37"89–94 cm	46–48"117–122 cm

How to measure

Use a soft tape, keep it level, and don't pull it tight — it should sit against you, not squeeze. It's easiest over a thin top or nothing at all.

Chest

Around the fullest part of your bust, with the tape level across your back and your arms relaxed at your sides.

Waist

Around the narrowest part of your torso, usually just above your navel. Breathe normally.

Hips

Around the fullest part of your hips and seat, with your feet together.

Every style has its own numbers

A size chart is a starting point — the real answer lives on the product page. We measure each style flat and publish the numbers on its own page under Fit & feel: chest, shoulder, length, sleeve, sleeve opening and hem, size by size. If you already own something of ours you love, measure it flat and compare.

Still not sure?

Tell us your measurements and the style you're looking at, and we'll tell you what we'd pick. We answer these ourselves.
