A pattern for brioche slouch socks, AKA slioche! And I have written the patterns for both toe up and cuff down! A really simple brioche pattern, there are brioche increases or decreases. You can work a two colour brioche or a single colour. Lends itself really well to a variegated and a solid or undyed.
This is worked on circular needles using magic loop method, and if you have the knowledge you can work 2 at a time with the toe up version (watch for tangles though!)

Adaptable to your size and preferences.

I used around 120g of sock weight yarn, this includes contrasting colour for brioche.
