Step aside, Kristen Stewart and Jennifer Lawrence.

Lily Collins is fashion's new IT girl for the young adult fiction-turned-movie franchise set.

For her first blockbuster outing in City Of Bones, the 24-year-old English-American actress - who portrays half-angel, half-human Shadowhunter Clary Fray in the fantasy film - made sure we paid attention.

And boy did she show she was no mere mortal on the red carpet.

Collins ran the gamut and scored major points for versatility, unpredictability and consistency.

Switching things up from sweet and sassy to sexy and stunning from one place to another, the newbie sure kept us on our toes.

1) At a mall event in Miami, Collins teased with demure straightened tresses and a loose-fitting silk Sachin + Babi floral watercolour print tee and matching skirt.

Not sure how those black suede Casadei pumps with gold trim got thrown into the mix, but I like her too much to nitpick.

Girly, pretty and flirty - from the ankles up.

2) I adored everything about this perfect daytime look for a meet-and-greet session in California.

Her shimmery slouchy blue-grey short-sleeved knit top partially tucked into a bronze knit pencil skirt from Bec & Bridge screamed effortless chic.

The breezy waves, chunky gold necklace and crystal-encrusted silver Christian Louboutin pointy pumps wrapped up the casual-cool ensemble nicely.

3) Collins served up major edge in this minimalist Cushnie et Ochs sleeveless ivory dress at the Los Angeles premiere, which was styled with matching Giuseppe Zanotti pumps, dark goth eyes and lips, and slicked-back side-parted locks.

It's tough to pull off an outfit with such gaping slashes at the bust and waist, but being blessed with a waifish figure means she can basically rock the heck out of a potato sack.

Somewhere, Rooney Mara is throwing a fit for not getting to it first.

4) Now this is what I call drama.

At the Berlin premiere, she morphed into a gorgeous glamazon by pairing a black Paper London sleeveless crop top with a black Halston Heritage voluminous maxi skirt. She managed to look modern yet retro, youthful yet elegant - thanks to her chunky gold jewellery, smouldering smokey eyes and low bun. Bravo
