Tie your tie and dress up like a man! We've spotted Rihanna, Alexa Chung, Kate Moss and Khloe Kardashian rocking the same trend: androgynous fashion. This huge spring trend, wearing black suits with a cool tie, is one of our absolute favorites this year. We'd match our suit with a cool red lipstick, just like Alexa. So suit up (as Barney Stinson would've said), and be the center of every party this spring!
