Aren’t you the one who swore you’d never make the same mistake twice? From screwed-up relationships to office politics, you’ve learned some hard lessons and mastered the art of protecting yourself. Why, then, are you always so unprepared for a simple thing like winter? If it’s lack of motivation, look no further. Get a parka from LaRok. Styled like a military jacket with an olive-green, wind-resistant cotton shell, it comes with a removable, beige faux-fur vest, which can be worn by itself on warmer days. Don’t put off getting one or you may find yourself pining away for the days when there was no waiting list. Another mistake you won’t want to repeat. Available at Poppy, 281 Mott Street, between Houston and Prince Streets (212-219-8934).
