Frequently Asked Questions
Everything you need to know about comfort and leakproof confidence.
How do I find my correct size?
We recommend using our comprehensive Size Guide found on each product page. For bras and underwear, you will need your bust, underbust, and hip measurements to ensure the perfect fit.
How do I care for my Knix products?
To maintain the integrity of our fabrics, we recommend machine washing on a cold, gentle cycle with mild detergent and laying flat to dry. Avoid bleach and fabric softeners.
What is your return policy?
We offer a 30-day Wash & Wear Guarantee on your first pair of underwear. For all other products, items must be unworn, unwashed, and in their original packaging to be eligible for a return.

Standard shipping typically takes 5-10 business days within North America. Expedited shipping options are available at checkout if you need your items sooner.
Do you ship internationally?
