This weekend Cara Delevingne, Rita Ora, Beyonce and Jourdan Dunn were in Chelmsford for V Festival. The campsite was flooded with jazzy tracksuits, black crop tops and denim cut-offs. Forget floral headbands, this year it's all about tummy flashing. But what happened beyond the VIP tiki huts at V? Lady Gaga is on a furious press tour for her new album, providing us with plenty of bonkers looks to dissect. Oh and Lily Collins has touched down in London - you're more than welcome to drop into Grazia HQ Lils. So what are you waiting for? See the best dressers so far this week in the gallery above...
The Week's Best Dressed: Lily Collins, Perrie Edwards, Beyonce & More
Rosie Huntington-Whiteley in Gerard Darel and Giorgio Armani bag- 21st August 2013
Rosie looks mega-polished in a Gerard Darel silk jumpsuit with a baby blue Giorgio Armani bag, Michael Kors sandals two strap heels and Miu Miu shades. Oh boy this is one of our favourite off-duty looks EVER.
Taylor Swift in Elie Saab at Press Conference - 20 August 2013
This has all the elements of a classic Taylor Swift look. Red lips? Check. Black mini shorts? Yup. Peep toe heels? Obvs. Elie Saab and Taylor Swift are a match made in pop heaven.
Lady Gaga out and about in New York, America - 21 Aug 2013
This week Gaga is changing her outfit (and wig) on the hour. This white trousers and sheer crop top combo is extremely elegant for Gaga.
Cate Blanchett in Roksanda Ilincic at 'Bue Jasmine' Sydney Premiere - 20 August 2013
Cate wore a Solero orange Roksanda dress with a folded neckline and capped sleeves. It's simple but beautiful.
Leigh-Anne Pinnock In AQ/AQ, Jade Thirlwall In Topshop & Perrie Edwards In Patricia Bonaldi at the ‘One Direction: This Is Us’ World Premiere' - 20 August 2013
Is that you Little Mix? The girlband have had a serious style-over as they have ditched the rainbow hair and graphic prints. Forget their usual style pick n' mix, the girls looked sleek and elegant.
Lily Collins in Paper London and Halston Heritage at ‘The Mortal Instruments: City of Bones’ Berlin premiere - 20 August 2013
Lily Collins and her tummy are back on the red carpet. This time she wore a rib-crazing Paper London crop top with a floor-sweeping Halston Heritage skirt. Once again Lils, we salute you.
Cara Delevingne out and about in London - 20 August 2013
This look is classic Cara. Beanie? Check. Statement trainers? Of course. Reflective sunnies? Duh. We heart the tartan trews.
Olivia Wilde in Crippin, Clover Canyon and Jimmy Choo on Good Morning America - 19 August 2013
Clover Canyon is fast becoming a new red carpet fave, as Solange and Olivia Wilde are fans of the colourful kaleidoscopic prints. Olivia toned down the elaborate pencil skirt with a black tee and blue Choos.
Mollie King in Preen Line at Radio 1 - 19 August 2013
Oh if only we could look this fresh the morning after V Festival. Mollie paired her Preen Line navy tartan dress with a classic Burberry bag and tan shoes.
Olivia Wilde in J. Mendel at 'Late Show with David Letterman', New York- 19 August 2013
Olivia Wilde is changing as many times as Gaga this week while on her promo tour for Drinking Buddies. We love this J. Mendel racer front dress with subtle cut-outs and A-line an skirt.
Olivia Wilde in Theyskens' Theory on 'Late Show with David Letterman', New York - 19 August 2013
Olivia wore a white Theyskens' Theory dress with a delicate sheer layer over the top to chat to Letterman. We love the graceful silhouette and simplicity of this look.
Lady Gaga in Balmain out and about in New York - 19 August 2013
Gaga went back to the 80s with this mohair jumper and silk white trews. She brought the two pieces together with a chunky gold waist belt.
Beyoncé Knowles in Roberto Cavalli at V Festival - 18 August 2013
Bey posted a #WhatI'mWearing' shot of her Spring 2013 Roberto Cavalli cantaloupe, mint and white printed maxi. But it's the champagne pob that has really got our attention...
Lady Gaga in Balenciaga at 'Good Morning America' TV show, New York - 19 August 2013
If you ignore the Casadei perspex stripper heels, this look is very refined for Lady G. The black Balenciaga by Alexander Wang LBD is super chic with a circular bodice and a tulip skirt. It's more Carey Mulligan than Mother Monster.
Rihanna in Rihanna for River Island out and about in Miami - 17 August 2013
[a target="_blank" href="/fashion/news/rihanna-is-the-best-advert-for-rihanna-for-river-island-autumn-winter-collection">Rihanna's Instagram has been taken over by her Autumn Winter collection[/a] for River Island. On Friday she did a triple, as she wore her mono print leggings, mono tunic top AND camo heels for a night with Jay Z in Miami.
Emma Watson in Out of Print jumper, J Brand dress and K. Jacques sandals out and about in New York - 15 August 2013
Gatsby fever is STILL a thing, as Emma Watson was spotted wearing a jumper covered with the iconic book jacket illustration. We want.
Lily Collins in Stella McCartney out and about in London - 19 August 2013
Oh Lils do you ever get it wrong? Our new style crush has jetted into London (squeal) and is already upping the style factor in a black Stella McCartney mini and Brian Atwood leopard heels.
Poppy Delevingne at Groucho Club, London - 15 August 2013
Poppy Delevingne wore ripped denim, a grey tee and a cosy gilet for a night out with Sienna Miller and Matthew Williamson.
