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.

Nora LaineAustralian Merino Wool^®

Our Australian merino has fine 17.5 micron fibers that feel soft against bare skin. The Woolmark^® label vouches for its fiber content, color fastness and shape retention.
With NATIVA^™, every bale is traceable to its farm of origin, and every farm is mulesing-free.
The Responsible Wool Standard (RWS) sets clear requirements for how the sheep are cared for and how their grazing land is managed.
Each piece carries the OEKO-TEX^® STANDARD 100 label: every thread, button and trim is tested for harmful substances.

Good to know.

This piece has a wide leg. 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.

100% merino wool, made in a 280 gsm twill cloth. You will find every detail under Fabric and details above.

Coarse fibers are what cause itch. Merino is far finer than ordinary wool, so it feels soft against bare skin. This piece measures 19.5 microns.

Every natural knit can pill a little where it rubs, under the arms or along the sides, mostly in the first few weeks. A sweater comb takes it off in a minute.

Less often than you would think: merino resists odor, so airing it between wears is usually enough. When it does need a wash, keep it cool, by hand or on a wool cycle, then dry it flat in the shade. Skip bleach and the tumble dryer.

Fold it instead of hanging it, so the shoulders hold their shape. Keep it clean in a drawer or a breathable bag, with a little cedar if moths worry you.

Comfortable all day

Thought wool trousers would be stiff and warm like a blanket. Comfortable all day, I sat through a long meeting and didn't once think about them. The M fits as expected. Pleasantly surprised.

Nice with my cardigan

I have the merino cardigan from here and wanted something to match, so I ordered the plum trousers. A colleague asked if it was a set. A bit looser through the thigh than I expected but still nice. Four stars from me.
