What to look for when buying a belt

what makes a good belt? What brand use high grain leather, and does it even matter?
Hey yall, horsesheep girlboy here

Looking to buy a belt for my bday upcoming in 2 weeks, I don't really have a good one at the moment and none that I can use in casual / formal settings.
I had my eyes on front office, Yohji and Lemaire but im not really sure what to look for.
I tend to like slimmer belts as they don't hug my gut as much as I sit down / lean over, if anyone has any reccs or any advice id love some

My wardrobe is mostly earthtoned + alot of navy and black. Preferably looking for a brown or black belt.
