Depends on the oxford. The white Thomas Mason oxford I got the shirt for my dinner suit made in is anything but informal.
Oxford is very versatile - some oxfords say summer is here - others seem all wintery and tweedy.
Its a great business shirt as an BD with tie slightly down from a suit but up from casual.
Will work for formal.
Its strength - the solid chunky texture is also its negative if you want a sleek, shiney, smooth look.
One of the few shirts that look good worn and frayed.
I noticed some summer jackets and pants made from oxford -haven't seen them in person ............
I used to use Valetudo shaving oil from shaver shop because its 100% natural, fragrance free and supposedly can be used for moisturising as well (simply wipe off excess after shave, don't need to rinse away). But then I thought stuff it and now I just use King of Shaves sensitive from any old supermarket. Works well enough.
I've been through Aesop Moroccan Neroli (good but too expensive), Kiehls white eagle (excellent but not all that cheap either), and a few English brands, as well as a few brands of shave oil. I've settled on the King of Shaves sensitive skin gel, as well as one of their razors. I have really sensitive skin and have to shave every day for work, and it's going well...
