areola slip
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.
