It is smart to buy rain umbrellas for January. Having one or two rain umbrellas on hand for this month is convenient because January rains a lot. Imagine being caught on your way to a friend’s house or an interview and it begins pouring. You look around the house and can’t find a suitable jacket or umbrella on hand. This means you need to buy a couple rain umbrellas to keep you dry. In January, the best colors are gray and purple. If you pick up some umbrellas in these colors, they will match all your other colors very easily.
