There are loads of different ways to wear a belt, for boys and girls. There are also lots of different styles of belts. Belts also go with different aesthetics.
In the summer how about trying some shorts with a fake leather belt.
Whilst we are stuck in lockdown why don't you try one of my shirts unbuttoned over one of my classic tees and then finish it of with a black belt or a shirt with a belt.
NEVER wear a belt around your neck!
