Frequently Asked Questions
Everything you need to know about your Knix experience.
How do I find my perfect fit?
We recommend checking our detailed Size Guide located on each product page. If you are between sizes, we generally suggest sizing up for the most comfortable fit.
What is your return and exchange policy?
We offer a 30-day return policy on most items. Please note that for hygiene reasons, certain intimate apparel must be unworn and in its original packaging to qualify for a return.
How should I care for my Knix garments?
To prolong the life of your items, we recommend machine washing in cold water on a gentle cycle and laying flat to dry. Avoid using bleach or fabric softeners.
How long will it take for my order to arrive?
Standard shipping typically takes 5-10 business days. Once your order ships, you will receive a confirmation email with a tracking number to monitor your delivery.
Do you offer international shipping?
Yes, we ship to many countries worldwide. Shipping costs and delivery timelines vary depending on the destination and will be calculated at checkout.
Are your products leak-proof?
Many of our products feature our patented Leakproof technology designed to handle periods, sweat, and light bladder leaks. Check the specific absorbency level on the product page.
