This head is usually used with a noname male doll. In history it has always been Ken sporting whatever outfit and role a male dolls is set out for. In the new millennia this changed and there was a lot of guys released that didn't have a true ID. Just no name dolls, as here a Groom - or a Prince.
The sculpt used for these dolls had a hair part slightly to the side with long bangs - molded.
