Size guide

Our pieces follow standard US women's sizing. Most styles come in XS to XL, and some also come in XXL. In short, go with the size you normally wear.

Which size to choose

  • Go with your usual size. That's the right choice for most women in most of our styles.
  • Between two sizes? Take the larger one for an easier fit, especially if you plan to layer underneath.
  • On each product page, Find my fit beside the sizes starts from the size you normally wear, and Fit and sizing shows the size worn in the photos where we have it.

How to measure

  • Bust: measure around the fullest part of your bust, keeping the tape level under your arms.
  • Waist: measure around your natural waist, the narrowest part of your torso, usually just above the navel.
  • Hips: stand with your feet together and measure around the fullest part of your hips.

Keep the tape snug but not tight. If one measurement falls in a different size from the others, go by your usual size and the fit you like.

Our merino

Sustainable Australian Merino Wool

Merino is not ordinary wool. Australia grows the finest merino in the world, and it is the only merino we use.

Soft against the skin

The fiber is a fraction of the width of a human hair, so it bends against the skin instead of prickling. It feels like fine cotton, and you can wear it next to the skin all day.

Warm when it is cold, cool when it is warm

The sheep live outdoors through hot days and cold nights, and their fleece evolved to cope with both. It keeps you warm when it is cold and lets heat out when it is warm.

Fresh for days

Wool pulls sweat away from the skin as vapor and holds up to a third of its weight before it feels damp. Odor-causing bacteria never get a foothold, so you can wear it for days between washes.

Fine gauge, close drape

We knit it at a fine gauge with a smooth, flat face, so it drapes close and looks as good under a jacket as it does on its own.

The standards behind it

  • WoolmarkWoolmarkFiber and performance
  • NATIVANATIVAResponsibly sourced wool
  • RWSRWSWelfare of sheep and land

Quick answers before you order.

Ask us anything else

This piece has a slim fit. Go with your usual size, and if you sit between two, take the larger one for an easier fit.

Yes. Tap Find my fit beside the sizes. It asks a few quick questions, starting with the size you normally wear, then suggests a size for this piece.

Where we have it, Fit and sizing above lists the size worn in the photos, so you can compare it with your own frame.

Not if it is cared for well. Wool shrinks from heat and the tumble dryer, so wash it cool, by hand or on a wool cycle, and dry it flat.

Return it within 30 days and the return is free. Then order the size you need.
