Knixteen promo code - November 2026

No discount code needed - just select Afterpay at checkout to break your total into four equal instalments with no interest. Available on all orders regardless of size, so you can stock up on period underwear and bralettes without paying everything upfront

Share your personal referral link from your Knixteen account page. When a friend places their first order using your link, they receive money off their purchase and you earn a credit to spend on your next order of bras, underwear, or loungewear

Final reductions are live on end-of-line products that are being phased out. These clearance items include limited sizes and colours, and once they're gone they won't be restocked. Discounts are already applied - no code needed at checkout

Buying period underwear in a pack works out cheaper per pair than buying individually. Knixteen offers multi-packs of their most popular absorbency styles, so you get several pairs for less than the combined single-item price

The sale section features discontinued colours and last-season prints at lower prices across period underwear, bralettes, and sleepwear. Sizes go quickly in popular cuts so it's worth checking back regularly for your size restocking at a markdown

Verified students can access a reduced price on their Knixteen orders. Verify your student status through the student discount portal linked on the site, and your discount applies to eligible full-price items including leakproof underwear and teen bralette packs

New subscribers get a welcome offer sent straight to their inbox. Pop your email into the signup box at the bottom of the Knixteen homepage and you'll receive a discount you can apply to your first purchase of period underwear, bras, or loungewear
