Sizing Guide

We know how difficult it can be to figure out sizing from measurements alone. We hope this makes it easier! Please email customercare@katharinalou.com for specific guidance.

We source our fabrics and deadstocks from all around the world. This means that each colour-way may slightly vary in measurements. So we recommend checking each product page.

How to Measure:

Waist

Measure around the smallest part of your waist — usually just above your belly button. Make sure you’re posture is relaxed.

Bust

Measure the fullest part of your bust. Keep the tape straight across your back and parallel to the floor. Don't pull it too tight – it should sit comfortably.

Hip

The Hip measurement is important for our skirts. Measure around the fullest part of your hips and bum, keeping your feet together and the tape straight.

Length

The Length measurement is taken from the top of the centre back, through to the bottom of the hem for all Maxi Dresses. For our Annabel Mini's the measurement is taken from top of the shoulder to bottom hem.

Fabric
Guide

✦✦✦

No one's really teaching us this stuff anymore — but lets take a hot minute and cover the essentials! At KLOU we're super intentional with our fabric choices and want you to know their traits & how to extend your garments life <3

  • SWIMWEAR: Recycled Polyester

    KLOU Swim is made from AceTex Recycle, which is made up of:
    → 84% Recycled Polyester
    → 16% Spandex.
    AceTex is a soft 4 way stretch recycled yarn. This means it stretches length wise and crosswise and thanks to the spandex, it returns to it's original shape after wearing.

    All our swim pieces are double lined, lightweight and quick drying. Wear her in the pool or the ocean as it's also chlorine and saltwater resistant.

  • HOW TO CARE FOR YOUR SWIMWEAR

    → To keep your swim pieces looking and feeling their best, rinse them thoroughly in cold water immediately after use to remove salt, chlorine, and sunscreen.

    → Hand wash separately in cold water and avoid harsh detergents.

    → Never roll up or pack your swimwear while it’s wet, as this can damage the fabric and affect its shape.

    → Always dry flat or hang in the shade to preserve colour and elasticity.

    → Do not bleach or iron, and avoid contact with rough surfaces to prevent pulling or tearing.

    → Proper care will help maintain stretch, softness, and longevity.

  • DRESSES, TOPS, BOTTOMS: 100% COTTON

    We love using 100% Cotton fabrics for our pieces. Here's some reasons why...

    Breathable → Keeps you cool in warmer climates.

    Natural Fibres → Gentle on sensitive skin with little to no irritation, compared to synthetic fibres.

    Durable → Lasts the test of time!

    We use 100% Cotton best we can for some of dresses, tops and bottoms.

  • HOW TO CARE FOR YOUR 100% COTTON

    → Always check the care label on the garment first, for any specific recommendations.

    → Use a gentle cycle with cold or lukewarm water and a mild detergent.

    → Place in a delicates bag for extra protection.
    → We always recommend hand washing for garment longevity.

    →Air-dry in the shade to avoid shrinkage and discolouration.
    By following these care instructions, you can keep your cotton pieces looking fresh and vibrant for many wears to come.

  • DEADSTOCK FABRIC

    Deadstock fabrics are surplus or unused textiles from garment factories, mills, and manufacturers. We choose to work with these materials as much as we can, for several important reasons:

    → They help reduce textile waste by giving new life to fabrics that might otherwise end up in landfill.

    → They lower the environmental impact by reducing the need to produce new materials.

    → They allow us to source high-quality, distinctive fabrics and create special, limited-edition pieces.

  • HOW TO CARE FOR YOUR DEADSTOCK

    As all deadstock materials we use vary in composition, we can't offer one set of care instructions. So we always recommend checking the care label before washing. If unsure, here's some things to note:

    → Avoid over-washing your garments! For a freshen up, hang your item outside (in the shade) to be aired out.

    → Hang up your garments to avoid creasing or the need to iron.

    →Cold hand wash with mild detergent if unsure (excluding wool blend fabrics).

    ♡ Because deadstock fabrics are limited and sometimes unavailable for reproduction, treat them with extra care — once they’re gone, they’re gone.

  • DENIM FABRIC

    We use 100% Cotton Indigo Denim for our Denim range. As seen on the Denim Mini & Maxi Skirts, and matching Denim Top. These pieces are some of our longest standing KLOU garments. Tried and tested for years. And here's some reasons why we use high-quality Denim:

    → 100% Cotton, thick and durable.

    →Indigo dyed surface, which naturally fades over time adding a more vintage look & feel.

    → Softens over time, which shapes to the wearers body creating a more personalised fit.

  • HOW TO CARE FOR YOUR DENIM

    → WASH LESS, WEAR MORE

    Denim doesn't need frequent washing. Only wash when visibly dirty or after several wears. Hang your denim up outside to air out in between wears instead.

    → Hand wash or use a delicate, cold cycle.

    Make sure you're using a mild detergent and washing your denim separately to any other items as the colour may transfer (especially in the first wash). Turn your denim inside out to help protect the colour.

    → Do not tumble dry. Always hang to dry in the shade.

    Heat will cause your denim to shrink and fade fast.

    → Store your denim folded or hanging by the waistband to maintain shape.
