Festival fashion may be synonymous with wellies and ponchos, but as temperatures soared at Glastonbury this week revellers embraced a far racier look.

Women have doused their breasts in sparkly paint and nipple tassels in a bold new trend that's been dubbed 'glitter boobs' - and it's not one for the faint-hearted.

On Wednesday night, party-goers at Worthy Farm made the most of the balmy weather and cast off their clothes to let it all hang out as they kicked off the hedonistic five-day music festival.

One performer set pulses racing in sequin-adorned hot pants and wore nothing but a pair of heart-shaped pasties to preserve her modesty.

Meanwhile, Instagram account @SparklesLdn were on hand to douse guests in glitter from head to toe.

The glitter boob trend - also dubbed 'disco t**s' - appears to be gaining momentum from fashionistas and festival-goers alike, with one blogger even declaring it a 'glorious alternative' to bikini tops'.

Yves Saint Laurent sent a model down the runway with an embellished nipple peeking out from beneath her dress for their SS17 show, and fashionistas have officially declared it a new trend.

A quick scroll through Instagram reveals how some brave souls have been dabbling with the trend for several months - in the guise of sequins, tassels and even glitter paint.

Berlin-based model Margaret Lamour wore a rhinestone-studded pair under a black sheer top, while burlesque dancer Minnie Tonka notched up dozens of likes after telling fans she was selling her extensive collection of nipple pasties - with 'removable tassels'.

And it's not just women trying out the trend, with a male 'pole performer' going by Sir Midnight Blues decorating his nipple with pink glitter and a bar - he told fans his secret tip was eyelash glue.

Similarly, cinematographer Jordan Rennert shared a picture of his friend Gerald sprinkling blue glitter all over his.

Fashion blogger Daisy Keens is one such devotee. She told FEMAIL: 'Contrary to being impractical or completely unnecessary, nipple pasties are a glorious alternative to bikini tops and, dare I say it, bras.'

Some took a more modest take on the racy trend; on Wednesday, one reveller slipped into an embellished crop top and high-waisted sequin pants for the first night of the festival

Revellers at Glastonbury Festival continued the party well into the night, following scorching temperatures on the first day of the famous event

'Depending on how comfortable you feel going braless (I have itty-bittiess so, in fairness, I have no real need for one!), nipple pasties and tassels can be worn on any number of occasions as a sparkling substitute.

'I’ve ditched bikini tops entirely in favour of a bedazzled pair of pasties (minimal tan lines, maximum shine) and I regularly wear them beneath sheer tees or lace tops in lieu of a bra. It’s all about confidence and comfort. Perfect festival attire if you ask me.'

Daisy recommends British label Ruth Melbourne, whose glittery accessories have adorned the likes of Miley Cyrus, or American brand Cheeky Cheetah.
