>>1860207Personally, I don't like the look of more than one patch per outfit. Excluding flags on backpacks or jackets obviously. It just feels like anything more makes you look odd. Either like one of those weird boomers who collects tonnes of pins and badges and wears them all pinned to one vest or like one of the kids in school who wore twenty LGBT, pop punk and meme patches every single day. Having one comfy patch and identifiable patch or two identifiable patches is my maximum.
For location, on backpacks I would say central on the back if you can and usually your priority identification on top then either comfy below or secondary identification underneath. For location on jackets or jumpers, I almost always say on the side of the left bicep with the same priority as backpack or one patch above the left nipple.
