“size smaller” — Needs review
Updated 2026-08-15 · Risk-term list version 2026-08-15c
“size smaller” is marked Needs review — it is not automatically a problem; it depends on the sentence you put it in.
Two readings: sizing advice ("if you are between sizes, take a size smaller") carries no risk; an outcome claim ("look two sizes smaller") is a quantified body change. Read the context — we do not decide it for you.
Say this instead: (if it is an outcome claim) a smoother waistline under fitted clothes. It belongs to the “The sizing grey area” family.

Why it is risky
Two readings: sizing advice ("if you are between sizes, take a size smaller") carries no risk; an outcome claim ("look two sizes smaller") is a quantified body change. Read the context — we do not decide it for you.
The same sentence can be sizing advice ("if you are between sizes, take the smaller one" — no risk) or an outcome claim ("you will look two sizes smaller" — high risk). That is why this family is always marked "needs review": the context is yours to read.
What to say instead
(if it is an outcome claim) a smoother waistline under fitted clothes
There is one rewriting rule: swap “what your body will do” for “what the garment does”. The first is a promise the product cannot keep; the second is what the buyer is actually paying for, and it is easier to shoot — a smoother line under a dress is filmable, a change in body weight is not.
Where this phrasing usually shows up
Across the samples we have scanned, this family shows up in these places, most common first:
- Size-chart notes
- What the creator says on camera
- Answers in the comments
The last two are the ones people miss: what the creator says on camera and replies in the comments. Neither lives in your documents, both are visible to the platform, and both are harder to fix after the fact.
What the regulator said
These are the regulator’s own words, not our paraphrase. This family has enforcement that matches the category exactly — not general advertising law, but a case about shapewear undergarments.
the companies are banned from claiming that any garment that contains any drug or cosmetic causes substantial weight or fat loss or a substantial reduction in body size. The companies also are prohibited from making claims that any drug or cosmetic reduces or eliminates cellulite or reduces body fat, unless they are not misleading and can be substantiated by competent and reliable scientific evidence.
FTC 新闻稿《FTC Approves Final Orders Banning Two Companies From Making Unsubstantiated Slimming Claims for Shapewear Undergarments》 · 2014-11
The two companies paid $1.3 million and $230,000 respectively for consumer refunds. Note the tail of the order — "unless ... competent and reliable scientific evidence": these claims are not banned outright, they are banned when unsubstantiated. Most cross-border sellers cannot produce evidence at that standard, which is why this list treats them as high risk. That is a risk judgement, not a legal determination.
We checked these pages word for word on 2026-08-15. Citing a regulator is not us making a legal determination — we do not issue compliance verdicts or legal advice.

FAQ
Is “size smaller” banned by the platform, or is this your ruling?
Neither. This is an item to check, compiled from published platform policy and advertising law. A match does not mean rejection; no match does not mean safe. We do not stand in for platform review and this is not legal advice — the platform’s review and your own legal judgment decide.
It is already all over my listing. Do I have to rewrite everything?
Fix in this order: (1) anything that goes into an ad (voiceover, captions, ad copy) → (2) the brief you send creators → (3) the listing → (4) your comment replies. The first two decide whether the ad runs, the third decides whether the listing stays up, and the fourth is the one everyone forgets.
What if the creator says it on camera?
The platform reviews the video that went live, not who wrote the line. So the brief needs a section that names the phrases which must not enter the voiceover or captions, and you repeat it when you confirm the sample shipment. See the creator brief template.
Does a synonym get me past this?
Past us, yes. Past the platform, no. A rule engine only reads the literal string; human and model review read what the sentence promises. Use this list to notice what you are promising, not as a gate you can pass.
What is the Chinese phrasing this comes from?
小两个码. Translation tools turn it into “size smaller” without hesitation, and it is 待核查 on the Chinese side too.
