Size guide
Getting the size right
Underwear only works if it fits, and you cannot try ours on before you order. Take two measurements, check them against the chart, and if you are still unsure message us — we answer in minutes.
Not sure which size you are? Send us your waist and hip measurement and we will tell you
what to order.

Caps are one size, adjustable at the back.
How the cuts sit
- Signature Boxer Brief. Mid-length leg. Sits low enough to stay put under trousers, short enough not to bunch behind the knee.
- Cotton Trunk. The same cut taken up an inch or two, for when nothing should show below a short.
- Racerback Bralette. Pull-on, no wire and no hooks. The band does the work, so it should feel firm across the ribs and not tight.
- Hipster Brief. Sits on the hip rather than the waist, with a bonded leg edge so nothing prints through.
- Knan Signature Cap. One size, adjustable at the back.
Measuring yourself
Stand relaxed, don't hold your stomach in, and keep the tape flat against the body without pulling it tight. Two of these are usually enough.
- Waist. Around the narrowest part, roughly level with your navel.
- Hip. Around the fullest part of your seat, feet together.
- Chest or bust. Around the fullest part, tape level across the back.
Then check them against the chart above. If you land between two sizes, see the note below.
Between two sizes? On boxer briefs and trunks, take the larger — the waistband takes up the difference, and a band that is too snug is the first thing to become uncomfortable. On the bralette and hipster our cut runs slightly small, so size up there too. Kids sizes are cut with growing room, so order the age.
Ordered the wrong size? Message us within
7 days and we will swap it, as long as the
