Selling used panties is not specifically illegal under any federal or state law in the United States. No statute bans the sale of worn underwear outright. The legal risk sits in the surrounding conduct: how you advertise the item, who you sell to, how you ship it, and whether you report the income. Keep those four things clean and the activity stays lawful almost everywhere in the country.
The Federal Obscenity Risk
The federal statutes that actually matter here are 18 U.S.C. § 1461 and § 1462. Section 1461 makes it a crime to mail any “obscene, lewd, lascivious, indecent, filthy or vile article, matter, thing, device, or substance,” with up to five years in prison for a first offense and up to ten for subsequent ones.1GovInfo. 18 USC 1461 – Mailing Obscene or Crime-Inciting Matter Section 1462 extends the same prohibition to shipments through any common carrier or interactive computer service, with identical penalties.2Office of the Law Revision Counsel. 18 USC 1462 – Importation or Transportation of Obscene Matters USPS, FedEx, and UPS all fall under this framework.
You will also see 18 U.S.C. § 1460 cited around this topic. It is not relevant: that statute only addresses obscene visual depictions sold on federal property.3Office of the Law Revision Counsel. 18 USC 1460 – Possession With Intent to Sell, and Sale, of Obscene Matter on Federal Property
A pair of worn underwear, by itself, is clothing. It is not obscene. What can push a listing toward obscenity is the marketing wrapped around it: graphic descriptions of sexual activity, explicit accompanying photos, or copy that presents the item purely as a sexual product. Courts use the three-part Miller test, and the hardest prong for prosecutors to prove is that the material lacks serious literary, artistic, political, or scientific value.4Justia US Supreme Court. Miller v California, 413 US 15 (1973) That is why standalone used-garment sales almost never generate charges. Federal prosecutors concentrate on pornography distribution, not niche physical items.
Two practical consequences follow. First, “community standards” are judged where the item is received, not just where it is sent, so a listing that is fine in one state can carry more risk when shipped into a more conservative one. Second, the easiest way to keep yourself out of this statute entirely is to keep listing text factual and restrained. Describe the garment. Skip the explicit narrative.
Age Is the Hard Line
Every participant in the transaction must be an adult. There is no gray zone here and no prosecutorial restraint to rely on. Federal law criminalizes involving minors in sexually explicit material, and while statutes like 18 U.S.C. § 2252 technically target visual depictions,5Office of the Law Revision Counsel. 18 USC 2252 – Certain Activities Relating to Material Involving the Sexual Exploitation of Minors6Office of the Law Revision Counsel. 18 USC 2256 – Definitions for Chapter a minor selling worn underwear in a sexual context draws immediate attention and gives prosecutors many tools to work with. Buyers who knowingly purchase from a minor carry the same exposure.
If you are selling, you must be 18 or older, and you need to be able to prove it. The niche platforms that permit these sales generally require a government-issued ID at signup for exactly this reason. Over 25 states have passed laws requiring age verification for access to adult content, and the Supreme Court recently upheld one such law, so expect these requirements to broaden rather than ease. Treat age verification as a prerequisite, not a formality.
State Sanitary Rules on Used Underwear
A handful of states have sanitary codes that regulate the resale of used clothing, with stricter rules for intimate items. These laws usually require sanitization before resale and sometimes require disclosure that an item is used. They were written for thrift stores and consignment shops, but they apply broadly to anyone selling used garments within the state. Violations can bring fines or loss of a business license.
Before listing from your state, check your local health code to see whether used-clothing resale is covered and what, if anything, you have to do to comply. This is a quiet rule that trips up sellers who assumed obscenity law was the only concern.
Shipping the Package
Ordinary worn clothing is not biohazardous and does not fall under USPS restrictions on “used health care products” contaminated with potentially infectious body fluids.7Postal Explorer. Publication 52 – Hazardous, Restricted, and Perishable Mail A problem only appears if a package leaks or arrives in a condition that suggests contamination, which can trigger inspection and cleanup protocols. The fix is simple: seal items in a leak-proof inner container before packaging.
Private carriers set their own rules. FedEx’s country-specific restrictions flag used underwear as a prohibited import for certain destinations, including Costa Rica, and some countries ban used clothing imports entirely.8FedEx. FedEx International Connect Country/Region Specific Prohibited and Restricted Items Check the carrier’s prohibited items list for any international destination before you commit to shipping there.
Reporting the Income
This is where most sellers in this space actually get into trouble, and it has nothing to do with the item being underwear. If you earn a profit, the IRS expects you to report it.9Internal Revenue Service. Hobby or Business: Here’s What to Know About That Side Hustle
The first question is whether what you are doing is a hobby or a business. The IRS weighs factors like whether you keep organized records, operate in a businesslike manner, depend on the income, and have turned a profit in some years. Selling consistently as a revenue stream points toward business classification. The practical difference: a business can deduct packaging, platform fees, and shipping costs against income, while a hobbyist cannot.
If it is a business, you owe self-employment tax on net earnings above $400. The rate is 15.3%, covering Social Security at 12.4% and Medicare at 2.9%.10Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Income and expenses go on Schedule C; the self-employment tax goes on Schedule SE.
Payment platforms may send you a Form 1099-K if gross payments exceed $20,000 across more than 200 transactions in a calendar year.11IRS.gov. Publication 1099 General Instructions for Certain Information Returns You owe tax on the income whether or not you receive the form.
Sales tax is a separate issue. Since the Supreme Court’s 2018 decision in South Dakota v. Wayfair, states can require remote sellers to collect sales tax once they cross an economic nexus threshold, most commonly $100,000 in gross sales into that state. Individual sellers are rarely close to those thresholds, but if you scale up, track your sales by destination state.
Platforms and Civil Exposure
Even where the law permits the sale, the platform may not. eBay and Depop prohibit the sale of used underwear in their terms of service, and listings get removed and accounts suspended for violations. Niche platforms that do allow these sales typically build their rules around the legal requirements already covered here: age verification, prohibitions on minors, and limits on how explicit a listing can be. Read those terms before you list.
Civil lawsuits are the other category of risk, and they almost always trace back to a lack of consent. Claiming the panties were worn by a specific person who never agreed to the sale can support claims for invasion of privacy, misappropriation of likeness, or intentional infliction of emotional distress, with both compensatory and punitive damages available. Sending items to someone unsolicited, or selling with the intent to humiliate or distress a specific person, can trigger similar claims even where no criminal statute was broken. When every party is a consenting adult and the transaction is private, these claims rarely surface.
What Actually Keeps You Legal
The pattern across all of this is consistent. Confirm you are an adult and never transact with anyone who is not. Keep your listing descriptions factual rather than explicit. Package shipments so nothing can leak. Check your state’s used-clothing sanitation rules. Report the income on your tax return, and treat it as business income if you are selling with any regularity. Sellers who follow those rules operate well inside the law.
