It is commonly speculated that Gwyndolin was a son of Lord Gwyn raised as a woman due to his affinity to the moon. Unsurprisingly this leads to him having feminine traits such as long hair, fair skin, and feminine clothing. But surprisingly he also has breasts. This is because the character model used for Gwyndolin is a female character model, despite the fact the character is actually male. This trait is also present in the Dark Souls Art Book.
