What purpose does character customization serve in Far Cry 5?

In Far Cry 5, players have the ability to customize their characters, pretty early on in the game:

However, I'm not seeing an explicitly defined benefit for doing so. I thought perhaps, since camouflage outfits are available that wearing them might help in stealth situations, but I've been unsuccessful in proving this.

The wiki is also unhelpful, simply describing what can be done in the character customization screen, along with the items that can be unlocked:

In Far Cry 5 the player can fully customize the player character with various items of clothing, hair styles, and even their gender. The clothing can be obtained through various methods, such as buying outfits in the store, unlocking them through missions, the Ubisoft Club, or by doing Live Events, among others.

This leads me to believe that it's purely cosmetic, but at that point, it's a first person game, so you as the player can't see your character. Do your customization choices show in the cutscenes at any point?
