Whether you're going out or lounging this weekend, here's some style inspiration that's got serious swag. Actress/model Dree Hemingway and model/socialite Mary Charteris are showing two sides of the tomboy here, a boy for day and a man for night (sounds about right).

Dree (pictured left) does day in a slouchy jumpsuit and sneakers — the contrasting casual sweater tied around the hips is your number-one tip here, while glossy red nails add a girly flash. Meanwhile, Mary (right) does night like a boss in Wolf of Wall Street power pinstripes. The trick to pulling off a double-breasted suit in style? The delicate chains dangling from her bag add just the right amount of feminine fab. (Bonus tip: the hand-in-pocket pose will prove you know what you're doing when you're snapped looking sharp.)

Cara and Suki take more styling tips from the guys in totally boss tailoring.
