Also known as: 輪チラ, ハミ乳輪, 輪モロ, 露出乳晕
When one or both areolae slip out of clothing or are partially exposed. The Nipples should not be exposed. Recognizable by a pink or red swell of flesh peeking out beneath the clothes.
This often happens with very Revealing Clothes, such as Slingshot Swimsuits or Micro Bikinis, or because of a Wardrobe Malfunction, Undressing, a Shirt Lift, or incomplete censorship.
If the Nipples are fully visible, tag Nipple Slip instead.
