Fab or flop: Elle Fanning's boho chic crop top, Rihanna's puffy-sleeve frock, and more

Fab: Minka Kelly

Kelly looks sensational in the bohemian-inspired maxi dress. She's channelling the best of the 70s which of course is coming back in 2015. The prints are gorgeous and just simple enough that they don't overwhelm her. We also love the oversized tote!

Flop: Rihanna

While the 70s might be making a fashion comeback this season, the 80s are not. Rihanna put a current spin on the "Pretty In Pink" look with this short, figure-hugging number. However, the sleeves just aren't doing anything for her and the overall fit isn't the most flattering. We like the chain necklaces, though!

Fab: Elle Fanning

Nobody pulls off this season's bohemian trend like Elle Fanning. We're loving her flared jeans and crop top. The actress proves that simplicity can go a long way as she rocks the look sans jewelry or heavy makeup. The platform shoes are the perfect accessory to the overall 70s style.

Flop: Natasha Lyonne

We always love a good floral print and a sophisticated mix/match outfit, but Lyonne's top and shirt just don't complement each other. We wish the skirt came with a matching top to form a trendy two-piece set. This outfit is just too busy.

Fab: Ashley Olsen

The Olsen twins are known to sport the best seasonal trends on the daily and this outfit is no exception. Flared jeans are making a huge comeback and, given how fab they look on Olsen, we understand why. We especially love the red belt she used to break up the navy-on-navy look.

Flop: Chaka Khan

While we always love an all-black getup in NYC, the items in Khan's outfit just don't seem to work together. Perhaps it's the different shades of black or maybe it's the different materials. We'd love to see a suede or cotton skirt without the shiny finish, and some height on the shoes would definitely go a long way.

Fab: Reese Witherspoon

The adorable Reese Witherspoon is at it again! The blue and white printed top is always a great option. Plus, Witherspoon accessorized perfectly with red shoes to add a fun pop to the outfit, a simple gold chain necklace, dark shades, and a black bucket bag.

Flop: Georgia May Jagger

While we like each individual item of Jagger's outfit, they don't seem to work perfectly together. The printed shirt is a bit busy to pair with such statement shoes and a darker denim would be a better fit with the top. We're also a bit confused about the green straps showing at the top of her shirt. She might be able to tie the outfit together if she ditched the green undershirt and swapped the shoes with a more neutral color to match her bag.

Fab: Nicky Hilton

Hilton looks cool and classic in this mixture of neutral staples. Hilton was brilliant to pair three different shades of white and off-white together for this outfit as it adds an edge to the all-white trend. We also love the go-to nude pumps!

Flop: Naomi Watts

While we adore the boyfriend jeans and slip-on sneakers, we just don't love the shirt. Watts appears to be swimming in the top so that it doesn't give off the trendy vibe she was likely going for. We also want to see her ditch the bag for a sleeker oversized tote.

Fab: Hailey Baldwin

We're not exactly sure what the deal is with that top, but we like it. We always appreciate the pairing of long sleeves with shorts. Plus, did you catch a glimpse of those shoes? Fierce!

Flop: Jenelle Evans

Evans' outfit is far too baggy for her small frame. She would look adorable and comfy if she swapped the sweatpants out for leggings or traded that Playboy top for a tight-fitting tank!

Fab: Alessandra Ambrosio 

Could this outfit possibly be any more adorable? Ambrosio pulls together an array of summer trends with the two-piece set, the crop top, the stripes, and the blue and white combo. She looks amazing!

Flop: Bai Ling

While crop tops and two-piece sets are both huge trends right now, Ling's outfit bares a bit too much for our tastes. While she has a great body that should absolutely be shown off, we can't help but feel like something's missing from this outfit. Perhaps she needs just one additional staple accessory to pull it all together.

Fab: Kate Bosworth

This is possibly one of our favorite Kate Bosworth outfits to date. The actress looks effortlessly chic in this gingham print shirt dress. The black suede ankle boots add the perfect touch and the ultra-dark shades make her look mysteriously cool.

Flop: Roseanne Barr

We understand that Barr was choosing comfort over fashion here, but we really think it's time for her to ditch the sleeveless top. The giant flower doesn't do anything for her. If she paired the jogger pants with even just a solid V-neck, she would pull off the athleisure look much better.

Fab: Kendall Jenner

Does Kendall Jenner ever have an off day? The model always looks flawless! We love her high-waisted jeans, oversized belt, and sleek bucket bag. The gold embellishments on her shirt perfectly complement the belt. Looks like someone's ready to kick off the fall season!

Flop: Alyson Hannigan

Hannigan's outfit is a bit too elementary here. She combined too many simple, solid staples when she could have had some fun to add a bit more flare. If she traded the pants for trendy culottes, traded the shoes for slip-on sneekers or wide-strap sandals, or swapped the top for something with prints, the look wouldn't be quite so plain. We also suggest she choose blue pants or orange bag rather than both at once.

Fab: Tamar Braxton

Braxton is showing us all how to work the sheer trend in the best way. This long-sleeve, extra-long sheer top is edgy enough without being overly revealing. The collar is a great contrast with the sheer and the white bandeau complements the look perfectly . We're also OBSESSED with those pointy-toe pumps!

As another final week of summer came and went all too soon, celebs began gearing up for the fall season by changing up their daily wardrobe. While some celebs effortlessly rocked the fall ankle boots and flared jeans, others appeared a bit confused and, as a result, downright frumpy. As they headed to local interviews, local coffee shops, or even their local gyms, we were right there every step of the way.

The bohemian look was the way to go this week as we saw many stars step out in flared jeans and crop tops, 70s-style prints, platform shoes, and vintage maxi dresses. We especially loved Minka Kelly's bohemian-inspired purple maxi dress. Elle Fanning was also a winner with her flared jeans, peasant-style crop top, and daring platform shoes.

While some stars rocked the throwback vibes, others sported the biggest flops of the decade. Rihanna, in particular, seemed a bit confused by the 70s trend, opting for an 80s-style puffy-sleeve pink lace dress that left us wondering if she was heading to a theme party. In addition, Natasha Lyonne struggled to master the mix and match print look that defined 70s style.
