most extemporary

You can embody the brand in a very direct way and I think Cath Kidston shows that in the most extemporary fashion.

I make no doubt but a man may be very formall in the most extemporary variety; & very fervently devout in the most wonted expressions: Nor is God more a God of variety, than of constancy: Nor are constant Forms of prayers more likely to flat, and hinder the Spirit of Prayer and Devotion, than an unpremeditated and confused variety, to distract and lose it.
