Protective finish for English Bridle Chair

[livewire516]

What would be a good finish for a sling chair, made from Bridle Leather? I am making another chair in the style pictured; however, it will be in a true navy. I'm using Wickett & Craig's 8 oz. English Bridle.

It will be a gift for my cousin; she has been asking me to make her one for years, ever since seeing the one pictured.

She collects handbags, and definitely prefers things look pristine, rather than having patina. (That puts me outside of my comfort zone: I generally use minimal finish, prioritizing preserving the hand-feel of natural materials and embracing signs of wear. But this gift is for her, so I'm trying my best to honor her tastes ).

What kind of finish will protect against the inevitable scuffs and wear? What kind of prep do I need to do with the hide being tanned like English bridle?
