# Labelling policy

The rules used to label the training data of the Try-On Safety Classifier.

## The question

Every label answers one question about the **output** of a virtual try-on:

> If we dress the shopper in this product, what will the generated photo show?

It is not about the product photo (a model may pose nude with a necklace), not about the marketing tone ("sexy",
"seductive", "boudoir"), and not about the shop. The title and description are used to know **what the product is**
and what it covers, never to judge tone.

## The four levels

`ok` < `revealing` < `lingerie` < `adult`. When a product is several things (a lingerie set with pasties), the most
severe part decides.

### ok: the shopper is shown normally dressed

The result is a photo anyone could post on a public social profile.

- Everyday clothes: tops, t-shirts, shirts, knitwear, outerwear, trousers, jeans, skirts, dresses.
- Skin-showing fashion worn as outerwear: crop tops, tube tops, backless or low-cut dresses, mini skirts, shorts,
  slit dresses, off-shoulder tops.
- Sportswear and activewear sold as such: sports bras worn as tops, leggings, cycling shorts, gym sets, football kits,
  leotards for dance or gymnastics.
- Full-coverage water sports gear: wetsuits, rash guards, burkinis, swim leggings, swim shirts.
- Sleepwear that covers like clothes: pyjamas, opaque nightgowns, robes, loungewear.
- Fashion pieces with a daring material or shape that still cover like clothes: leather or vinyl trousers, latex-look
  dresses, corsets or bustiers worn as tops, fashion chest harnesses over clothes, chokers.
- Costumes and cosplay that cover like clothes, with no sexual framing.
- Not clothing: bags, shoes, hats, glasses, jewellery, watches, wigs, hair products, cosmetics, pet wear, home goods.

### revealing: swimwear-level coverage

The result shows the shopper the way a swimwear catalog would.

- Swimwear: bikinis, swimsuits, monokinis, tankinis, swim briefs, swim trunks, including small string, triangle,
  brazilian or cheeky styles and "microkinis" with small but complete cups. Board shorts that cover like ordinary
  shorts are `ok`.
- Men's underwear: boxers, boxer briefs, briefs, trunks.
- Shapewear of any gender.
- Cover-ups and sheer layers whose photos show a bikini underneath.
- Micro skirts or micro shorts that expose the buttocks.

### lingerie: women's underwear and lingerie

The result shows the shopper in underwear or lingerie.

- Bras, bralettes, balconettes, demi bras, bodices sold as lingerie, lined or not.
- Panties, briefs, knickers, thongs and G-strings sold as women's underwear, and open-back or caged briefs with a
  closed front.
- Lingerie sets, babydolls, teddies, chemises and slips sold as lingerie; bodysuits sold as lingerie or shown worn
  without bottoms in a lingerie shoot.
- Garter belts, suspenders, lingerie harness straps, stockings or stay-ups sold as lingerie; corsets and cinchers worn
  as lingerie.
- Sheer, mesh, tulle or lace lingerie where nothing intimate is clearly visible. If nipples or genitals are clearly
  visible through it, it is `adult`.

### adult: intimate areas exposed, or a sexual product

The result would show nipples, breasts, buttocks or genitals bare or barely covered, or the product's purpose is
sexual.

- Truly micro swimwear: cups barely covering the nipples, a bottom barely covering the genitals, extreme slingshots.
  The word "micro" in a product name decides nothing.
- Body chains and body jewellery made to be worn on bare skin with nothing underneath. A body chain styled over a top
  or dress is `ok`.
- Nipple coverage only: pasties, nipple covers, nipple stickers, tape, tassels, nipple jewellery.
- Intimate areas actually visible: lingerie, dresses or tops where the photos show nipples or genitals clearly
  through the fabric.
- Open designs: open-cup, cupless, crotchless, peek-a-boo, cut-outs over nipples or genitals.
- Bondage, restraint and fetish items, whatever they cover, including BDSM pieces that look like ordinary clothes
  (bondage or straitjacket dresses, locking or padded BDSM collars, rubber garments sold as fetish wear): body
  harnesses, cuffs, collars with leashes, gags, rope, pet-play gear.
- Fetish suits, whatever they cover: full-body leather, latex, PVC or rubber suits and catsuits, gimp suits, zentai
  worn as fetish wear.
- Fetish masks and hoods: leather or latex hoods, pup or dog masks, gimp masks, furry and fursuit heads.
- Sexual role-play costumes (nurse, maid and similar sold for the bedroom).
- Sexualised anime and cosplay outfits: character costumes cut or styled to be sexual (lingerie-style cosplay, bunny
  suits, skimpy character bodysuits).
- Anything at `revealing` level or above that is shown on a drawn or anime figure instead of a real person or mannequin.
- Wearable sex toys, and fetish-themed accessories or merchandise.
- Any product whose photos are nudity rather than a garment.

## Subject

Who or what the product is for, independent of the level.

- **human_clothing**: worn by a person. Garments, underwear, swimwear, shoes, bags, hats, glasses, jewellery,
  watches, body chains, costumes, fetish wear.
- **pet**: made for an animal. Pet harnesses, collars, leashes, clothes and costumes. Pet-play gear made for humans is
  `human_clothing` and `adult`, not `pet`.
- **not_clothing**: not a garment or accessory. Cosmetics, skincare, perfume, hair products, wigs, home goods, toys,
  gadgets, images with no product.

## Tags

Tags add detail without changing the level.

- **swimwear**: only for pieces made to be worn as swimwear (bikinis, swimsuits, monokinis, swim tops and bottoms).
  Skirts, shorts, costumes, bodysuits, rave sets and underwear thongs are `not_swimwear`, even when shown at the beach.
  - `regular`: ordinary bikini or swimsuit coverage.
  - `near_micro`: string, thong or G-string bikinis and small cups that still fully cover, including microkinis with
    complete cups and a fully covering pouch.
  - `micro`: nipples or genitals barely covered or exposed.
  
  `regular` and `near_micro` are `revealing`; `micro` is `adult`.
- **ravewear**: festival and rave outfits (rave bras and bodysuits, fishnet or rhinestone festival sets, chain tops,
  holographic or LED pieces). Most ravewear is `revealing`; ravewear over bare skin with pasties or visible nipples is
  `adult`. Pasties on their own are not ravewear, and swimwear made of rave materials (fishnet, holographic, sequin)
  shown as swimwear is not ravewear.

## How each product was labelled

1. Read the title and description to know what the product is and what it covers.
2. Look at every photo to see coverage: lined or sheer, worn alone or styled with other clothes.
3. Pick the level from the rules above; the most severe part of the product decides.
4. Mark the label as unsure when a careful reviewer applying this policy could pick another level.
5. Pick the subject and the tags.
6. Any product whose photos could show a minor in a revealing or sexual context, including childlike drawn or anime
   characters, is not labelled and is removed from the data for good.

Labels were produced by a large language model following this policy after viewing every photo. A human reviewer
checked calibration examples for every level and tag and corrected the boundary cases.
