I don't think the role of style is different for a woman of any age. Style, to me, is about experimenting with what gives you pleasure, a joyous expression of imagination. I emphasize joyous because too much is written about fashion that takes the pleasure away - clothes that make you look thinner or clothes that make you look younger or, horrors, clothes that make other people envy you or that - double horrors - are "age appropriate".
So it follows that those who have reason have freedom to will or not to will, although this freedom is not equal in all of them. [. . . ] human souls are more free when they persevere in the contemplation of the mind of God, less free when they descend to the corporeal, and even less free when they are entirely imprisoned in earthly flesh and blood.
