Fab or flop: Katy Perry's skin-tight jumpsuit, Ariana Grande's see-through jacket and more

As models shopped around Manhattan after being casted in the Victoria's Secret show and other stars roamed the streets of L.A. to catch up with friends this week, they all made efforts to sport their best November style.

We especially loved Naomi Campbell's look this week (similar style here). She dazzled in a gorgeous raspberry suede jacket, open-toe heeled booties and an adorable fringe clutch. She looked chic and flirty in all the right ways. We were also obsessed with model Romee Striid's outfit as she turned heads throughout NYC (get the look here). She sported leather pants, fierce heeled combat boots and a sleek white top with cutout shoulders. We love the belt, choker necklace and over-the-shoulder bag she paired the look with!

As for flops, the biggest mistakes we saw this week were celebs sporting unflattering outfits or items that seemed a bit low in quality. For example, we weren't fans of Ariana Grande's transparent jacket. We're still not sure if it's a rain jacket or not, but either way we'd like to see her trade the staple with something a bit more elegant. We also didn't love Angelina Jolie's blue frock in NYC this week. It's not the most flattering dress we've seen her sport and the soft blue color and nude heels seem to wash the star out a bit.
