What Is Dear Kate?
Known issue: our tracked referral link (via ShareASale) is currently returning “this link is inactive” rather than Dear Kate’s referral offer page — we’ve flagged it internally to get it fixed. Until then, click through to dearkate.com directly and use the newsletter signup for 20% off instead.
Dear Kate isn’t a tampon or pad replacement — it’s a backup layer. The underwear is built to absorb light leaks and spills (Dear Kate has historically cited up to about 3 teaspoons of liquid) using their “Underlux” moisture-wicking, antimicrobial fabric, without the plastic-y feel of some leakproof underwear. If your primary protection fails or overflows, this is the safety net.
We confirmed dearkate.com is live and actively selling as of our last check — the current lineup runs from period underwear (hipsters, briefs, thongs) to leak-resistant activewear and a maternity/postpartum collection. Dear Kate was founded by a chemical engineer who set out to build activewear-grade lingerie for real bodies, and that’s still the core pitch.

Dear Kate has historically run a refer-a-friend program where both you and the friend you refer get $15 in credit. We can’t currently confirm that exact amount is still live, since our own referral link is down (see above) — treat $15 as the historical figure rather than a guaranteed current one, and check the terms once you’re on their site. What we can confirm right now is the 20%-off newsletter signup and the buy-3-save-15% bulk discount, both live on dearkate.com as of our last check.
Frequently Asked Questions
Is there a Dear Kate promo code to type in?
The confirmed current offer is a 20%-off code sent when you sign up for Dear Kate’s email list — no separate code needed beyond that. Their historical $15 refer-a-friend program may still exist, but we can’t verify its current terms since our tracked link is down.
Are these a replacement for tampons or pads?
Dear Kate positions them as backup protection against leaks and spills, not a primary replacement for tampons or pads. Some period-underwear brands market themselves as a standalone replacement — Dear Kate’s own framing has traditionally been backup/spill protection instead.
Does couponsuck’s referral link give an extra discount?
It’s meant to, but as of this rewrite the tracked link isn’t loading correctly. We’re leaving it in place and flagging it for a fix — in the meantime, the 20%-off newsletter signup is confirmed live and doesn’t need our link to work.
When was this page last checked?
We confirmed Dear Kate was live and selling in July 2026. Promo terms can change without notice, so confirm the discount applies at checkout.
