Every man should wear a belt. Even the smaller ones. We bought our (Tinie-)Junior. Is as so very slim, it will also need it. However, it is also a matter of elegance. Every man should have a black leather belt.
Pros
Easy to wash and care for, making it a hassle-free option for everyday wear.
Cons
The collar may not lie flat or stay in place, affecting the overall look of the shirt.
