Taylor's stage attire varies wildly from thigh-skimming shorts to futuristic foil skirts, but one thing remains: they serve to showcase her enviable figure.

One eye-catching number is a figure-hugging sparkling bodysuit with a nude neckline panel and matching heeled booties.

There are several crop tops of choice, which feature sparkly embellishment or luminous encrusted panels.

At one point, the blonde beauty transformed her high-octane look for something a little more dangerous, as she performed hit song Bad Blood in a black all-leather look.

Another look saw her take to the stage in a revealing white bandeau crop top, matching high-waisted shorts and black suspenders with over-the-knee suede boots.

Other stage costumes embrace a more feminine look, as leggy Swift performed songs in a number of flirty foil skater skirts in blue and purple.

The cast of X-Men: Apocalypse and The Art of More were present. Nicholas Hoult, Sophier Turner, Rose Byrne and Kate Bosworth had a VIP section at the end of the cat walk.

Well plaid Taylor! Keep your style in check with an Asos bikini

Taylor Swift never endures any Blank Spaces when it comes to her fashion sense.

The flaxen-haired pop singer has her signature style down and is known for her love of retro inspired pieces, so it didn’t come as a surprise to see her favor a high waisted bikini over an itty bitty one.

Working a checked two piece from Asos, Taylor proved she’s still a normal girl with a penchant for online shopping in the now reduced bikini, and it suited her throwback fashion sense perfectly with its bodice style top and high bottoms. No wonder Calvin can’t keep his hands off!

A classy alternative to a traditional triangle tie up bikini, this two piece will sure get heads turning on your next holiday so we suggest you snap it up now before it sells out.

Simply click (right) to make it yours in time for your summer getaway, because it's now down to $44.50. Woop!

Considering the beautiful models and other celebrities present at the party, it may not be surprising that some - like Gigi and Taylor in a photo posted by the former - even managed to look sexy in fancy pajamas.

'Star spangled blondies,' Gigi wrote to caption the photo, which also showed Martha. 

The group changed out of their onesies for some baking, perhaps not wanting to get icing all over those special outfits.

Taylor posted two photos showing the group involved with the project, one of which saw seven young women working together to frost a single cake.

'Making our flag cake this morning because we're Barefoot Contessa fangirls,' the singer explained in the caption.

A second photo showed the finished project - Taylor's younger brother, Austin, lit sparklers atop a sheet cake decorated to look like a flag with icing and fruit.

Ed's appearance at the shindig gave Taylor an excuse to make a dig at the expense of British-American relations.

'When Ed shows up in a red coat for the 4th of July because he just can't let it go,' Taylor wrote to caption an Instagram on Saturday.

In the picture, the defiant singer posed proudly in a red military jacket of the type that might have been worn by the British army during the American Revolution.

As for Taylor and Calvin, romance was heating up during the party.

On Friday, Taylor shared a lovey-dovey photo of herself getting a piggyback ride from her Scottish boyfriend along with the caption: 'Friendly relations between Scotland and America.'   

Taylor, 25, jumped on the back of her boyfriend's muscular body, wrapping her arms around his neck and smiling from ear to ear.

The 1989 hitmaker wore a plaid print bikini including high-waisted bottoms for a retro look.

Clearly a romantic ode to her lover, the lyrics seem to reference the nature of their headline-grabbing romance.

'You stand with your hand on my waist line. It's a scene and we're out here in plain sight. I can hear them whisper as we pass by. It's a bad sign,' she sang. 'Something happens when everybody finds out. See the vultures circling dark clouds.'

Then, reaching the chorus while making eye-contact with Calvin, she continued: 'Love's a fragile little flame, it could burn out. Cause they got the cages, they got the boxes and guns. They are the hunters, we are the foxes and we run. Baby, I know places we won't be found.'
