Take a look at the original:
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 wanted to fix it this way:
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.
To add a comma between style and he would cause an equally bad problem, a comma splice. A comma splice occurs when you have two complete sentences joined with a comma alone. Alphonso does not care as much about comfort as he does about style is the first complete sentence. He will wear, for example, a long sleeve shirt and a leather jacket ... begins the second complete sentence. The spot between style and he needs a stronger break than a comma alone.
