You can go about this in a roundabout fashion. (A direct approach might not work too well.)

You can ask a woman whose opinion means something to you what qualities they find appealing in a man as well as what qualities do they find unappealing.

After having a generalized discussion about these points, the opportunity may come to shift the conversation to more specific details that relate to you personally.

Whatever they have to say, just keep the conversation light and then just thank them for their time.
