She's the sartorial queen and ELLE cover alumna that's forever on our street style radar, topped our best dressed list at this year's British Fashion Awards (that feathered Prada two-piece was everything) and if we could, we'd own that white Victoriana blouse from her M&S collection ten times over - yup, we're talking about Alexa Chung.

The master of balancing nonchalant indie cool with hot off the runway haute couture, Alexa Chung's insouciant approach to dressing impeccably puts our wardrobe game to shame.

So when we dropped by to check out the presentation of her debut eponymous clothing line, we had high hopes. And, as expected, we weren't disappointed.

Sending a 'corrupt broody school girl gang' down the aisles at St Katharine's church to the Ruchard Curtis-esque soundtrack of a children's choir singing 'Good Vibrations', Chung's collection was all 70s boarding school girl gone bad.

Think ditsy print maxi dresses with satin dolly flats finished with a hood and smudged liner. Sort of a Red Riding Hood who's seen things Granny couldn't even imagine vibe.

Add to that pastel pink PVC pinafore dresses, knitted sweaters paired with mum jeans and a collared shirt, and the silver sequin dress of our Diana Ross disco dreams, and you've got one major collection with every outfit our Summer 2017 wardrobe needs right now.

We caught up with the model-turned-tv presenter-turned-designer and all round style icon to talk all things the Alexa collection…

Who is the Alexa Girl? What Would She be Doing With Her Saturday?

'The girl is probably someone like Lily Sumner who walked in the show, she had the peroxide blonde hair. I think on a Saturday she'd be hungover in the morning, then she'd go and get a taco in New York and then she'd go back to her room and draw some pictures or think of a song and then she'd go out all night and play pool and have fun and probably be hungover again the next day.'

How do you want people to feel when they're wearing your clothes?

'Cool. I want them to feel cool. And we talk about that a lot and it's so basic to boil something down to that one word which in itself implies something which is not cool at all. But I think it either is, or it isn't really.

'And we work hard at proportions to make them insouciant and easy and breezy and authentic. I mention in the office a lot that things need to do what they say. If we've got a winter coat it needs to actually keep you warm and I don't like things that have got things or a shoulder where you're like 'Wait… is that a shirt? Or is it… an accordion?' It needs to be what it is.

'But that's because I'm a bit boring and I like classic clothes and I think it's the way you style it that makes it interesting.'

In your press release you describe something as 'lascivious lilac' - we love that. How are you bringing sexy back?

'I think by celebrating individuality and personality. We made an effort to cast girls who have their own sense of personal style and were believable in terms of that they might have actually made that choice to wear that sort of outfit.

'To me someone that's confident - that's so cheesy to say - but when someone really knows themselves and is unafraid, that is appealing and makes them sexy. You know sometimes you meet people that shouldn't be sexy [by conventional standards] and you're like, oh, they're cool!'

We heard Daddy Chung created an illustration for your collection...

'Yeah, he did the George Harrison drawing for the pink sweatshirt. He did it in the 60s so I just cut it out of his sketchbook and slapped it on the sweatshirt.'

So other than snapping up Daddy Chung's illustrated pink sweatshirt (available at alexachung.com), how else can we channel the Alexa Chung boarding school bad girl?

It's all in the hair and make-up.

Creating three different looks inspired by a young Brooke Shields, David Bowie and Princess Diana, hair stylist and founder of BLEACH London, Alex Brownsell, had her badass retro references on point.

How To Get The Young Brooke Shields Big Blowout By Alex Brownsell

Step 1

Spritz damp hair with L'Oréal Professionnel Tecni Art Pli and rough dry with a hairdryer and your hands.

Step 2

Blowdry hair away from your forehead to create volume in the front. Then grab large sections in the lengths and twist while drying to create texture.

Step 3

Spritz with more Tecni Art Pli, then take three different width round brushes and roll up into sections of hair to create a range of textures.

Alex's Top Tip: Sounds totally wrong, but leave the brushes in for hair that looks like it's been 'grabbed'. Edgy.

Step 4

Take the brushes out and spritz with hairspray likeL'Oréal Professionnel Infinium before using your fingers to separate the ends.

Alexa Chung Make-Uppinterest

As Alexa said, it's all about celebrating the individual cool girl, which means two different make-up looks.

Models were split into two camps: the girl sipping a modest glass of champers on the Kings Road with a complexion so good it inspires 'skin envy', and the girls that partied all night and never went home, working smudged liner and raw skin.

The key products? It's all about Charlotte Tilbury.

Mix the Magic Cream with the Healthy Glow tinted moisturiser for model-worthy skin in an instant.

A swipe of Rock n Kohl pencil liner in Bedroom Black (So. Cool.) for that 'I haven't even gone to sleep' look and you're good to go.
