Best Selling Underwear

Among the best-selling products on the online store are Knix bras, including contour, no-wire bras that are padded, supported, and offer 18-hour comfort options. 

Knix swimwear and the Knix evolution tank bodysuit are designed to fit women of all ages and sizes and hold in any saggy midriff areas, while the Knix thigh saver underwear eliminate sweat and chaffing.

Consult the Knixwear sizing chart on the website to ensure that you get the correct clothing for your body shape. Also, consider aftercare instructions to keep your purchases in mint condition. 

Wash your underwear in cold water with mild detergent and lay out flat to dry. Avoid fabric softener or bleach during laundry, and for best results, toss all underwear in a lingerie bag or machine-wash with similar items on the cold cycle.

Delivery and Returns Options at Knix

Shop for items on the Knix online store and pay using all the major debit/credit cards or your PayPal account. Enter any Knix discount codes or your Knix promo code to enjoy further savings on your order.

Use a Knix free shipping code or order goods worth C$100 or more to enjoy free delivery. Orders take 2-4 days to arrive at the GTA, 3 - 10 days for urban areas, and 6-15 days for remote locations. Any orders under C$100, cost C$10 to Central Canada, and C$20 to the NWT, Yukon, and Nunavut.

The Knix returns Canada policy states that all Knix bras and tops (including bodysuits) are eligible for return or exchange within 30 days of delivery. Swimwear and underwear do not qualify for returns for hygienic reasons, as well as items sold during sales events.
