That's jean-ius!

Now that her sisters Mary-Kate and Ashley Olsen have been cranking out their own fashion-forward clothing lines, Elizabeth Olsen has picked up a few stylish "tips" of her own.

Clad in a black Acne T-shirt and a colorfully chic Erdem skirt, the younger Olsen sibling sported a creamy blue, denim-inspired manicure at a NYLON/Armani Exchange event in NYC on Wednesday.

Dark and dramatic polish colors will be popping up for fall and winter, but this dark, dusty blue is the perfect way to rock a bold hue without looking goth in black or navy blue.

To get the 22-year-old Martha Marcy May Marlene actress' look, try Illamasqua Nail Varnish in Force ($14,

Or, to achieve a full-on denim look, try Sally Hansen Salon Effects Real Nail Polish Strips in Skinny Jeans ($10, -- the design looks just like your favorite dungarees.
