From the streets to the red carpet, here are the most notable celebrity looks of the week, featuring a striking suit for Katy Perry, Anna Kendrick channeling a sultry 70s sleuth, and Gwen Stefani's unfortunate resemblance to a mushroom.

THE BEST

It seems the author of Fantastic Beasts and Where to Find Them also knows where to find the best dressed celebrities. At the premiere of her book-turned-movie, Rowling, who herself stunned in a gold and silver gown with plunging neckline, was complimented by a dashing Eddie Redmayne in a picture perfect, patterned suit.

The songstress opted for an unconventional pantsuit at a recent Hollywood event. We love the bold black and white blocking and the angular element to her top. It's a polished look, right down to that stunning blue nail varnish.

She may be coming out the other side of a messy divorce but Amber Heard looked radiant at the annual Glamour Women of the Year Awards. Layers of frills and lace in pale pink would wash most of us out, but with the help of a red lip, this is a strong look for Heard.

Amy Adams

Even thought she's just wrapped up two major films, Amy Adams' looks fresh and relaxed in this easy day-time outfit. Her flared jeans paired with thick pumps and a longer-sleeved tee give her an elongated look.

Talk about girl on a mission: Anna looks like she means business in this statement trench paired with pointy metallic heels and large sunglasses. We feel a role in a spy flick coming on.

THE WORST

Gwen Stefani

Perhaps she was attempting to recreate past red carpet moments, but unfortunately the soft tulle and brown tones do little but conjure up images of mushrooms rather than the glam look she was surely going for.

Rapper or not, Kanye can't seem to pull off this oversized look. His black shearling jacket looks like it's about to fall off his shoulders and his hoodie resembles the blanket wrapped around E.T.

We're all about dressing for comfort, but Gigi literally wore pyjamas to an event this week. Not even her chic heels and crystal choker were enough to disguise them.
