whether I should buy a coat or not

I felt cold on the way home recently. Actually I don't have a coat, so I only wear a undershirt, a shirt and a suit. On November I think I don't have to buy a coat because my company is very close to the station. I felt cold between dormitory and station(ABIKO). So If I only endure cold during that section, there are no problem about cold.

But on December, I couldn't say that. I became feeling terriblly cold in the morning and on the way home. Now I use gloves and scarf when I commute. But I have to rethink whether I buy a coat or not.
