There is no permit for shapewear claims
Updated 2026-08-15 · Risk-term list version 2026-08-15c
No. There is no certificate, filing or licence that unlocks slimming claims for a garment. Sellers ask this because other categories work that way — cosmetics in China have a registration and filing regime, and supplements in some markets have notification schemes. Apparel does not.
So both directions fail: “get the paperwork and you may say it” is false, and so is “you may not say it because you lack the paperwork.” The risk comes from what the sentence promises — a smoother line under clothes, or a change to the body itself.
That line is not ours. It is the one the US FTC drew in its 2014 orders against two caffeine-infused shapewear sellers, quoted verbatim below.
Why sellers look for a permit that does not exist
Two habits collide here. Sellers who also handle skincare are used to a world where an efficacy claim is tied to a filed product category, so they assume apparel has an equivalent. And search results for “banned words” tend to merge general advertising-law lists with cosmetics guidance, producing an obligation that matches neither.
The practical cost of the confusion is real: teams spend weeks chasing a certificate that does not exist, and meanwhile the listing copy that actually gets ads rejected goes untouched.
What actually decides the risk: the garment, or the body
| What you mean | Reads as an effect of wearing it | Reads as a change to the body |
|---|---|---|
| Flatter midsection | a smoother line under a fitted dress | lose 5 lbs, lose inches |
| Looks slimmer | looks smoother under clothes | burns fat, boosts metabolism |
| Support | back feels supported through a long day | corrects posture, relieves back pain |
| Skin | (do not go here) | reduces cellulite, removes cellulite |
| Effortless | wear it all day | no diet or exercise needed |
The left column is not a “safe” column. It is what the sentence looks like once the promise moves off the body and back onto the garment. A match is not a rejection and a clean scan is not safety — every page of the flagged-term list says so.
The regulator’s own words
Worth quoting rather than paraphrasing:
the law draws a sharp distinction between a suggestion that a certain kind of underwear may help people look or feel better while wearing it vs. an affirmative representation (especially one supposedly supported with scientific evidence) that it will reduce cellulite, shrink hips or thighs, and destroy fat.
FTC · Shape up your shapewear claims · 2014-09
The final orders bar claims that a garment containing a drug or cosmetic causes substantial weight or fat loss or a substantial reduction in body size, and claims that it reduces or eliminates cellulite or reduces body fat, unless substantiated by competent and reliable scientific evidence. The two companies paid $1.3 million and $230,000 for consumer refunds.
Note the tail: these claims are not banned outright, they are banned unsubstantiated. Most cross-border sellers cannot meet that evidence standard, which is why our list treats them as high risk. That is a risk judgement, not a legal determination — we make no compliance ruling and give no legal advice.
A note on jurisdictions
Searching this question in English often surfaces UK and Irish advertising-standards guidance — BMI floors, maximum safe rates of weight loss, rules on who may appear in the ad. That guidance is real, but it is a different jurisdiction from the US market most cross-border shapewear sellers are actually running in.
This page is about the US market: US platform policy plus the FTC action above. If you run in the UK or the EU, the rules that bind you are not the ones on this page, and we have not covered them. We would rather say that than let you assume our coverage is wider than it is.
Three steps to move a sentence off the body
- Find the subject. Is the subject of this sentence the buyer’s body or the garment? “Lose 5 lbs” has a body as its subject; “smoother line under a dress” has the garment.
- Delete quantified body promises. Pounds, inches, dress sizes, weeks — if a number is attached to a change in the body, delete the sentence rather than softening it. “Lose inches” to “noticeably slimmer” swaps a measurable promise for a vague one; the risk stays.
- Cut mechanism language. Burns, metabolises, detoxes, boosts circulation — all of these describe something happening inside the body, which a garment does not do and you cannot substantiate.

FAQ
What about a lab test report — would that let me make the claim?
It depends what was tested. Fabric composition and compression values are measurable. “Wearing this makes you lose weight” is not something a fabric test can establish. The two companies in the FTC action did have studies; the problem was the studies themselves — unblinded, uncontrolled — and advertising a single statistical outlier as a typical result.
Can I use the word “shapewear” at all?
Yes. It is the category name and using it to refer to the product is normal. The risk is in turning it into a promised outcome — the noun (a shapewear bodysuit) and the verb (shapes your body) are different sentences. That is why our list flags “slimming” as an outcome word while leaving the category name alone.
Does this mean my ad will be approved?
No, and we never say that. Platform review looks at the video, the audio, the landing page and your account history — none of which we can see. A clean scan is not approval, and a match is not a rejection. The platform’s review and your own legal judgment decide.
How do I verify what this page says?
Open the two FTC pages linked above; they are public and we list the date we checked them. Every hard claim on this page carries a link. We would rather you check than take our word for it — that is the whole point of publishing the list and its sources.
