This SecretUndies review examines a small marketplace where adults sell worn underwear, socks, swimwear, shoes and custom items. It promises privacy and clear fees, and we wanted to see whether that is enough to make it worth joining.
We worked from its public marketplace, fee tables, seller and buyer guides, Terms and privacy policy, most of them in German. We did not buy or list anything, so delivery and support speed remain untested.
Everything here is for adults aged 18 or older.
Key takeaways
- SecretUndies is run by SecretUndies Ltd in Larnaca, Cyprus, and mainly targets German-speaking countries.
- Sellers pay €4.97, €14.97 or €29.97 a month, plus a platform fee of 20%, 15% or 5% per sale.
- Payouts start at €50 by bank transfer and arrive no earlier than 21 days after shipping proof.
- The homepage loaded no outside trackers before consent, which is unusually good for this niche.
- Age checks are not mandatory at signup, and seller verification is vaguely defined.
- The catalogue looked almost empty when checked, so SpicyRanked scores it 5.5 out of 10.
What Is SecretUndies?
SecretUndies is a person-to-person marketplace for worn intimate items. The platform hosts the shops and payments but is not a party to the sale itself.
It offers around ten language versions, yet its Terms say the service is aimed at Germany, Austria and Switzerland. Every shop seen in the review was based in Germany.
Dark Ero keeps a dedicated buy used panties category if you want to compare this niche at a glance. Its wider fetish directory covers related marketplaces too.
How SecretUndies Works
Each seller gets a small shop with listings, a chat inbox and order tools. Buyers browse, message the seller, pay through checkout and confirm once the parcel arrives.
What Buyers See
The marketplace lists dozens of categories, but SpicyRanked found only a handful of live listings, all from one seller. Prices ranged from about €15 to €80.
Buyers can also post a request describing what they want. With so few active shops, we cannot say how often those requests are answered.
How Selling Works
A free account lets you build a profile and a few private draft listings. To publish, you must buy a monthly plan, and listings are still reviewed.
Product photos must not show faces, recognisable tattoos or other identifying details. Explicit images and body fluids are banned outright.
If you are weighing worn items against photos, the Dark Ero hub on how to sell feet pics and its list of the best platforms for content creators show what other routes look like.
SecretUndies Fees and Seller Plans
There is no separate buyer fee that we could find. Buyers pay the item price plus shipping shown at checkout.
- Starter: €4.97 a month, 20% platform fee, up to 5 active products.
- Premium: €14.97 a month, 15% fee, up to 30 products, verification and one weekly boost.
- VIP: €29.97 a month, 5% fee, unlimited products and two weekly boosts.
On a €50 sale, a Starter seller keeps €40 and a VIP seller keeps €47.50, before the monthly plan. Extra boosts cost €5 for 24 hours or €10 for a week.
Payouts
Payouts start at €50 and go by bank transfer. The Terms say money is released no earlier than 21 days after valid tracking or proof of shipping.
Disputes, refunds and chargebacks can delay that further, and sellers carry chargeback costs. Stripe may also ask for ID before paying out.
Is SecretUndies Safe?
It is reasonably safe for buyers who keep every step on the platform. Its checks on who is actually selling are thinner than its marketing implies.
Age and Seller Verification
All users must be 18 or older, and SecretUndies may request proof at any time. We found no mandatory age check when an account is created.
The verified badge is bundled with the Premium plan and its check steps are not explained. Even the help pages say a badge is no guarantee.
Payment Protection
Buyer money is described as held until the buyer confirms the order, with Stripe processing card, SEPA and Klarna payments. Sharing phone numbers, emails or outside payment links is banned and filtered in chat.
Any request to pay off-platform is a classic scam sign. The Dark Ero guide on avoiding seller scams and this independent list of six common selling scams apply equally to worn items.
SecretUndies Privacy
Privacy is where SecretUndies shines. Its homepage made no outside requests before consent and set only two first-party cookies.
Hosting is with IONOS in Germany under a GDPR agreement. Transaction records are kept for up to 10 years for tax reasons, which is normal.
Sellers should use a parcel locker or pickup point rather than a home address. Dark Ero's safety guides include more tips on staying anonymous.

Best SecretUndies Alternatives
For a bigger panty marketplace, read the SpicyRanked Snifffr review or the All Things Worn review. Both have far more active buyers.
If you would rather sell feet pics online than post physical items, the SpicyRanked FeetFinder review covers a platform that ID-checks sellers. Dark Ero's own FeetFinder review and its ranking of the best sites to sell feet pics offer a second opinion.
Creators who want subscriptions instead should see the SpicyRanked list of sites like OnlyFans to make money and Dark Ero's sites like OnlyFans guide.
An independent SecretUndies seller breakdown is also worth a read before you commit.
SecretUndies Verdict
SecretUndies gets privacy, payments and fee clarity right. What it lacks is buyers, sellers and firm age checks.
We give it 5.5 out of 10. It could suit privacy-minded sellers in the DACH region, but most people will earn more on a larger marketplace today.
