Sydney Studio pickup

Alternatively if you would like to pick up from our Sydney Studio, you are welcome to DM us on Instagram or contact us  here to organise a time.


All items are sent in 100% recycled or compostable mailers.


What's your return policy?

  • As my garments are made in limited editions, refunds are not provided for change of mind.
  • This includes if you change your mind or if the item does not fit.
  • SWIMWEAR is strictly no refund or exchange due to hygiene reasons.
  • Please use the size guide information listed below to make sure you match yourself to your correct size or you can leave your own measurements in the notes when you checkout

Can I exchange to a different size?

If your order doesn’t fit I can offer a size exchange dependant on available stock and production timelines. Limited to one size exchange for the same item per order. I do not offer alterations to orders once sent. 

For exchange of size please email customercare@katharinalou.com within 3 days of delivery and the team will let you know what is available and provide you with a returns address. The return postage as well as postage back to the customer should be paid for by the customer. 


Do you have a size chart?


All measurements are in CM.

How to measure yourself

Relax your stance and measure around the fullest part of your bust.

Measure the widest part of your lower body (this should be your bum)

Measure around the smallest area of your waist, make sure you aren't breathing in so this measurement isn’t too tight!

Measure from your shoulder point down to your ankle (where a maxi dress would sit) This means I can hem a mini/midi or maxi from this measurement!

Wrap your measuring tape around the top of your arm (where the elastic for the sleeve would fit) so that we can make sure its not too loose or tight.

Wrap your measuring tape around your wrist (only need this for long sleeves!)
