bare pectorals
When one or both pectorals are exposed while the character is wearing upper-body clothing, or is in the middle of undressing.
This includes wearing revealing clothes, torn clothes or open clothes etc.
Do not use this tag in situations where a male character is nude or topless.
If the pectorals are partially covered (e.g with tank tops), use pectoral cleavage, underpec and/or sidepec instead.
