A little TLC for your piece

🌸 How to Care for Your Posey Pants

Your Posey Pants in Jett Black are soft, flowy, and built for all the lounge days and coffee runs life throws at you — here’s how to keep them feeling fresh:

Wash me gently – Cold hand wash is best for my rayon fibres. If you use the machine, pop me in a delicate bag on a gentle cycle.

Stay cool – Hot water can shrink or warp me, so stick with cold washes only.

Dry with care – Air dry flat or hang me in the shade. Please skip the tumble dryer — I like to keep my flowy drape and relaxed fit.

Smooth me out – If I wrinkle, a gentle steam will bring me back to life. Avoid hot irons directly on my fabric.

Store me well – Fold me or hang me in a cool, dry place. Keep me out of long sun exposure so my Jett Black stays bold and deep.

Garment measurements, not body measurements. The measurements listed are of the finished garment, not your body — clothing is designed with ease for comfort and movement.

Measuring your body: Use a soft tape measure directly against your body. Measure your waist at the narrowest point and your hips approximately 20 cm below your natural waist.

Compare to a favourite piece: Measure a similar garment you already own and love, then compare to our size guide for the most accurate fit.

Between sizes? We generally suggest sizing down as our clothing is designed to be flowy. Measurements may vary by 2–3 cm as each garment is measured by hand.

✦ All measurements are garment measurements in centimetres. Our pieces are intentionally cut with ease — this is not a fitted style and that's exactly the point.

Grab a soft fabric tape measure. Stand naturally, feet together. Measure over underwear or a single lightweight layer for the most accurate results.

The Three Measurements That Matter

01 Bust

Place the tape close under the armhole at the fullest part of your bust. Measure from side seam, around and back to the same side seam.

Keep the tape parallel to the floor — snug but not tight.

02 Waist

Measure at the narrowest point — usually 2–3 cm above your belly button. Place the tape from side seam, around and back.

Exhale naturally before taking the measurement.

03 Hips

Place the tape approximately 20 cm below your natural waistline at the fullest part of your hips. Measure all the way around.

Stand with feet together for the most accurate result.

Sizing tip: Our styles are intentionally cut with generous ease. If you're between sizes, we recommend sizing down — the garment ease will still give you that effortless, relaxed look without overwhelming your frame.

Still not sure on sizing? Our team knows every style — we're here to help.
