nearly naked apron

Like naked apron but with a slightly less bare torso, due to the apron being worn in combination with something light and revealing, usually underwear or swimsuits/swimwear.

If the apron is combined with a significantly more modest outfit, then just use the normal apron tag. Conversely, if the additional clothing lacks any coverage of the torso or is explicitly allowed by the nude tag's guidelines (headwear, legwear etc.), then the naked apron tag is still preferred over this one.
