Objectification of a person is when you view them as having nothing to contribute except sexual pleasure for another. Thus, viewing her as a sex object, like a blow-up doll or a dildo.Dats what I' been asking.
How does a woman being in a bikini "objectify" her?
So, no, a gown that does not force attention directly to their primary and secondary sexual assets and erogenous zones is not objectifying her, nor is demonstration of a non-sexual skill.
Unless you have a baton-twirling fetish or something, then you might be able to produce hard-core porn that no one else even recognizes as sexual in nature.
So, you see a woman in a bikini and your thought is "she has nothing to offer but sexual pleasure"?
I think the problem is on your end.
