Shirts are very versatile and they can be worn with other pieces in your closet but the question remains. Do you wear it tucked or untucked?

The answer to that question really depends on you gentlemen and your personal preference, I know for myself, I tend to wear a shirt untucked when I am going for a casual look paired with shorts or jeans or casual pants.
Factors that determine whether you can wear your shirt tucked:
1) The type of dress shirt – a solid dress shirt with no patterns or graphic designs is key. Go for colors such as black, blue , white and dark red. These shirts in general are worn tucked with formal pants.
2) Design
3) The formality of the event – if you are attending a formal event such as weddings, galas and award ceremonies, this usually require a dressed up look , shirts must always be tucked unless you are going for a casual style.
4) The type of hem

5) Collar
6) The Fabric or Material
