Product & Sizing Information

Knix bra sizing might be a bit different than what you're used to. Sizing can be a bit tricky, but we got you covered! 

You can check out all of our size charts and measure for your bra size below:

https://knix.com/size-guide 


Washing your underwear shouldn't be complicated, so we designed our products to be super easy to wash and care for. For best results, machine wash on cold with mild detergent, and either tumble dry on low (Super Leakproof Underwear) or lay flat to dry (all other Leakproof products). That's it! 

Pro tips: Don't use softener or bleach and never iron.

Finding your Knix fits tight at first is totally normal. Our bras and tops are designed to mold to your unique shape. For that reason, you'll probably notice that the fit will be tight when you first put it on. Our innovative fabrics actually stretch and relax to support your body. Basically, this means you're wearing the bra - the bra isn't wearing you!

We encourage you to wash and wear your Knix as much as you like for 30 days. Take the tags off, go for a run, dance around your house, throw it in the washing machine - do whatever you do in your usual bra! If you're still not feeling the fit during your first month, let our Knixperts know at [email protected], we'll help you find the right size!

We also offer a new Personal Shopping Experience in our Retail Stores that you might be interested in!

This in-store shopping experiences includes a private fitting and dedicated one-on-one assistance to help find your correct size and style. It will also give you the opportunity to explore our full collection and recommendations from one of our amazing Knixperts!

Discounts, Store Credits & Gift Cards

Yes! You can add the recipient's name, email and a personalized message.

Knix Gift Cards are handled by our partner team, Totus.

Our dedicated partner, Totus, will be able to help you out directly. They're the experts on this one and can get things sorted quickly.

You can reach them by:

They're available Monday through Friday, 8am to 5pm CST.

Before reaching out, it'll help to have your gift card number handy (you can find it on the back of the card) so they can look into things right away.

Here are a list of a few common issues why your gift card may not be working:

  • Insufficient gift card balance
  • Incorrect gift card code
  • Website restrictions

Gift card balance:

  • Ensure there's enough balance on the gift card to cover the purchase. If the gift card is new and it was delivered electronically, you may refer to your original email received to check the value. If you have a physical gift card, you may check the front of a gift card for the value.
  • For any other questions regarding the balance of your gift card, let us know and an agent can assist you.

Incorrect gift card code:

  • Double-check that the gift card code matches the code in your email or the back of your physical gift card. (Even a small mistake can prevent the card from working).
  • Be careful not to mistake a "0" (zero) for an "O" and a "1" (one) instead of the letter "I", or vice versa.

Website restrictions:

  • Gift cards must be applied on the Knix web domain they were purchased from. Example: a Knix gift card purchased from knix.ca or from a Canadian retailer must be used on the Knix Canada website or at a Canadian retail location.

If none of these situations apply to your gift card issue, it's possible that a technical problem is preventing the card from processing. In this case, we'd be happy to create a support ticket and escalate the issue to an agent for further investigation.

Discount codes and rewards points can not be applied towards the purchasing of gift cards. If you have other items in your order, the discount code or rewards points will apply to the other products, but not the gift card.

We are currently unable to support scheduling a gift card for a future date or time. The gift card will send automatically to the recipient at the time of purchase to the designated email address.

If you are unable to find you gift card in your inbox, please check your junk mail and promotional mail folders as sometimes our emails will get caught in filters. If you are still unable to find it, let us know and we're happy to help you find a solution!

We offer free standard shipping to most of North America for orders of $100+. If you are spending over $100 and still are charged shipping in the checkout, there could be a few reasons why:

  • Free shipping thresholds are calculated after discounts, before shipping, gift card costs and taxes. Please be sure that the discounted total is above $100 before taxes.
  • Reward points will be considered a discount and purchases will need to be above $100 after points redemption.
  • Your total includes a gift card purchase. Because gift cards are not shipped they do not apply towards the free shipping threshold.

If you meet the above criteria and are still being charged shipping, we'd be happy to look into any mix-ups for you!

We don't currently have a Knix gift card balance checker at this time. To check if you still have available funds on your gift card, proceed to checkout and enter your gift card code in the Discount code or gift card field. If you have available funds, they will apply to your purchase.

If you happen to be at a Knix retail location, they can check your balance in-store.

If you have any other questions related to your Knix gift card balance, please let us know so we can connect you to an agent.

We offer a variety of discount codes throughout the year. The best way to be eligible for a discount code is to sign up for our promotional emails and SMS messages. You can sign up for our emails at the bottom of our website page.

If you're having trouble finding where to enter your discount code, ensure that you have made it to the checkout page by clicking "Checkout Now" from your shopping bag. Once you are on the checkout page, the discount code field is directly below your cart.
