If you're going to buy one thing this month, buy it green. I know next month is actually the time to celebrate green, but why not start early? It's always ideal to be an early adopter in the world of fashion. But seriously, all signs are pointing to verde amore — the love of green. I recently found out it's one of my friend's favorite colors; my bridesmaid debut this month is in an emerald green (J.Crew) dress; today is St. Pat's day; and these funky fresh Lanvin sandals make me giddy. Flip on for some verde amore . . .
