Review the original item:
Alphonso does not care as much about comfort as he does about
style he will wear, for example, a long sleeve
shirt and a leather jacket in the middle of a Florida summer if they are
the perfect complement to his new pair of khakis.
You chose the correct way to fix the error:
Alphonso does not care as much about comfort as he does about
style;
he will wear, for example, a long sleeve shirt and a leather jacket
in the middle of a Florida summer if they are the perfect complement to
his new pair of khakis.
Alphonso does not care as much about comfort as he does about style is a complete sentence. He will wear, for example, a long sleeve shirt and a leather jacket ... begins the second complete sentence.
You are always correct when you use a semicolon to join two complete sentences that are closely related in meaning.
