The hormones will be OUT of control. The collective thirst of the audience was SO real. Girls LOST their shit every time headliner Austin Mahone flashed his abs or busted out some sultry dance moves. There will be tweens. The audience probably was 95% pre-teen and teenage girls. One girl who couldn’t be much older than 20 sitting near me said she felt “so old” at the concert, so that should paint a picture of the average age in attendance. Also, their parents and siblings will be there. However, they won’t be enjoying the concert as much. Mom wasn’t going to let the girls go to the concert alone, was she? There were a fair amount of parents (dads too!) in the audience, along with some even-younger siblings. For the most part, they sat down and persevered. But I saw at least one mom get super into it — she danced along the entire time. There will be screaming. There may be no louder sound that thousands of teenagers screaming for Austin Mahone’s abs in unison.

Maybe that’s why so many of the parents brought earplugs. And when the audience isn’t screaming, they’ll be singing. Mahone paused from singing to let the audience fill in for him, and did a bunch of call-and-response with the crowd. screwfix hoodiesThe crowd was loud, proud, and they knew ALL the lyrics by heart.run muc hoodie A YouTube/Vine sensation will be the opening act.screwfix hoodies Shawn Mendes was the first opener. j dilla hoodiesIf you haven’t heard of him before, he’s a 15-year old singer who was discovered on Vine. s2000 hoodiesHe’s been killing it on iTunes and, with his single “Life of the Party,” he is the youngest-ever artist to chart on the Billboard Hot 100. hoodie drug slang

Most important: He is a major item for the tweenagers of America. One girl sitting near us commented that she “shouldn’t feel that way about a 15-year-old.” You’ll also see a girl group perform. Fifth Harmony from the second season of The X-Factor were the second opener. the north face denali hoodie fleece jacket women's saleThey got major cheers for every booty pop, and their new girl-power anthem “BO$$” perked the audience way up. And a boy band, too. None of British group The Vamps’ songs are on Spotify, so I didn’t know what to expect of their set. Perhaps I shouldn’t have been surprised when four teen guys in black skinny jeans walked onstage. The Vamps are basically like One Direction meets 5 Seconds of Summer (Lead singer Bradley Simpson even kind of looks like Harry Styles) and the girls were IN LOVE. Other internet celebrities will be there.

Before Mahone went on, the audience kept SCREAMING in short bursts. This wasn’t a weird teen ritual — they were shouting out to someone in the balcony. The girls behind me weren’t sure who the person in the balcony was: First they thought it was Vine star Cameron Dallas and rapper Jake Miller. But it was actually the singer Becky G (she sings a hit song called “Shower”). Also, it looks like YouTube star Tyler Oakley was there. Welcome to 2014, people! Austin will have so much charm and charisma. He’s got dance moves, a great stage presence, a million-watt smile, and DON”T FORGET those abs. He knew how to work the stage, and had the entire audience for the course of the evening. He will also remind you of Justin Bieber. From the parachute pants to the “swagger” Mahone was like an updated version of Justin Bieber, sans the douchebag attitude. There will be SO MUCH choreography. Fifth Harmony had the sassy hair toss thing down; Austin Mahone and his backup dancers knew how to move on stage.

Everyone’s show felt really rehearsed, but you can’t deny these kids have moves! Everyone in the audience will be Austin’s girlfriend for the evening. One general premise of Austin (and Shawn Mendes and The Vamps) is that they are the kind of clean-cut guys you’d want to bring home to mom. In the middle of his set, Austin tries to find the “perfect girl” in the audience, then brings one ~lucky~ Mahomie onstage for a special serenade. You’ll be told you’re “beautiful” over and over. Mahone and The Vamps kept telling audience how “beautiful” they all were. The audience did NOT mind, and these proclamations garnered even more screams. You’ll hear some covers. Mahone covered John Legend’s “All Of You.” The Vamps did a bunch of covers: a Jason Derulo track, “Cecelia” by Simon & Garfunkel and “No Woman No Cry” by Bob Marley. It’s possible the 13-year-olds in the audience didn’t know some of those, but it didn’t stop them from continuing to scream and dance along.

The concert will go by VERY fast. These acts don’t take their time getting to the stage. Shawn Mendes went on exactly at the scheduled 7:30 p.m. start time, and the concert moved quickly from there — no intermissions, and only a quick pause between acts. The whole thing was over in about three hours. For that, every parent in the audience was eternally grateful. And, ABOVE ALL, at the end of the evening your ears will be ringing. But hey, did you expect any different?As a style enthusiast, I'm always looking for hot new blogs and brands to feed my sensational appetite for fashion, photography and inspiration. In the last year or so I've increasingly been influenced by Australian style blogs. It started with one, and a few recommendations later I'm officially obsessed with Australian style. Their girls pull off this effortlessly chic, surfer off-duty look. They have exquisite individualistic style, a penchant for reinventing classic looks and the country is churning out some of the top style influencers worldwide.

Check out five Aussie wonders whose charisma, style and unique point of view have been blowing my mind. 1. Christine CenteneraThis past summer Centenera had industry insiders buzzing when she left Harper's Bazaar Australia to join newly appointed editor-in-chief Edwina McCann at Vogue Australia as the senior fashion editor. Centenera is a hot commodity right now. She consulted for Kanye West's debut women's wear collection in Paris, she was a stylist for Australian media darling Lara Bingle and she's quite the street style star herself scoring recurring spots on The Sartorialist, Jack & Jill and Street Peeper to name a few. But Centenera is not your average Aussie beach babe. She's a master of the unexpected pairing. She rocks cutting edge couture with sweatpants and counters feminine looks with sex appeal and edgy accoutrements. She's the only woman (besides Emanuelle Alt) that can inspire a color lover like me to roll out in black from head to toe and feel comfortable, confident and anything but average.

2. One TeaspoonBooty shorts. That's how I stumbled upon this stand out rock and roll glamor-infused brand. If you're looking for the perfect booty shorts to wear all winter over opaque tights, one that stops just below the bum cheek and has a little extra flair that you can't always find at your local Levi's store, this brand is for you. I first spotted their Bandit Denim Cutoffs as I was searching for Coachella gear and it was love at first sight! They were comfortable, showcased my legs from groin to ankle and included an adorable camouflage print - the perfect booty short! Jamie Blakey started One Teaspoon in 2000 from her bedroom floor at just 21 years old. Today One Teaspoon is carried in over 200 stores in Australia and their international footprint is steadily growing as U.S. favorites such as Free People continue to restock their merchandise. I look forward to the evolution of One Teaspoon as they continue to present the epitome of rebellious cool. Read more after the slideshow.

3. They All Hate UsA blog filled with so many glorious fashion shots I have it bookmarked as my homepage for early morning inspiration as I arrive to the office and sip my tea. What better way to start your day than with beautiful imagery of gardens and stilettos, oceanic views and killer beauty shots? I'm a big fan of Elin Kling and Miranda Kerr so their frequent cameos are always welcome along with a plentiful collection of street style. The geniuses behind They All Hate Us are Tash, a buyer for a leading youth retailer in Australia and Elle, a visual merchandising manager for an Australian swimwear label. They consider the blog an inspirational montage of all things they love with the hopes that it will make you smile too. 4. Tony BiancoI began to gain interest in this precious strappy sandal I kept seeing on the streets of Melbourne. It was so simplistic it could be worn with anything, but so classic it had the power to be a stand out piece all alone. This type of diversity is hard to come by so I immediately set out to find what could be the signature staple of my wardrobe.

It took a couple days of research to verify this masterpiece I so craved was designed by Tony Bianco. Tony Bianco is a leading Australian footwear brand. They aspire to attract the street-smart modern woman with shoes that embody the attitude of High Street London and the spirit of Soho NY. So I visited their website, found my shoe for $150 (plus a couple code that made them $100) and proceeded to check out online. I thought it was almost too easy until seconds later when I realized Tony Bianco only wants Australians to wear their shoes. Domestic shipping only, it seemed, as I continuously received a bright red error message when inputting my New York address. But I was not about to let a little thing like shipping keep me from obtaining the clutch piece my wardrobe was missing. I emailed the corporate head quarters in Collingwood Australia and after 38 emails with Alex the amazing office receptionist, me mailing them shipping labels, and $36 in shipping fees I had my shoes and I haven't looked back since.

5. Sass & BideSass & Bide believes "life's too short to wear boring clothes" and I concur. Perhaps this is why I adore the designers and their products as much as I do. Or maybe it's their impeccable attention to detail, their juxtaposition of powerful fabrics, their contradiction of traditional styles as they create runway looks or simply their support for our president Barack Obama. Either way, they're my girl crush. Sass & Bide is the namesake label of Sarah-Jane Clarke (Sass) & Heidi Middleton (Bide), a former accountant and advertising art director who started the line with a customized pair of jeans. Their full range of merchandise is available in over 20 countries and is stocked at online favorites like Asos. If you're in the market for a cocktail dress for New Year's Eve or just a sick pair of jeans, you can't go wrong with Sass & Bide. They have a rad blog as well in case you're in need of a little sasspiration. In 2013, Sass & Bide will open its first New York flagship store which will join its 18 boutiques located in Australia and New Zealand.
