The all-encompassing moment of leaving school (apart from leaving school) is undoubtedly the prom (queue high-pitched squeals). And whilst we may not be as enthusiastic as our American counter parts, every girl knows the prom is all about the ultimate evening dress. And what dress could possibly be better than one designed especially for you by the uber talented team at Topshop?

That’s right, Topshop are offering two very lucky ladies - one from the UK and one from the US - a chance to have the dress of their dreams created exclusively for them by the design gurus at Topshop. Gone are the fears of someone turning up in the same dress as you – all you have to do is create a mood board on Pinterest showcasing all the styles, colours and inspirations for your ultimate prom dress. Whether it’s inspired by the latest in red carpet dresses or by women on the street style circuit, the choice is totally up to you. 

To enter, simply create a Pinterest board called ‘Topshop Prom Queen’ and remember to include the hashtag #Topshoppromqueen. Include at least three product images from Topshop, as well as a picture of yourself. Finally click here www.topshop.com/promqueen to fill out the entry form and include a link to your pinterest board. The competition closes on the 15th of March and will be judged by Creative Director Kate Phelan as well as the Toppers design team. Winners to be announced shortly after...

So what’s in store for the lucky two? (Other than the dress) Well, not only do they get whisked off to London, see the dress of their dreams being created in front of their eyes, but they also get (deep breath) a £250 shopping spree! What's more, in true prom spirit, Topshop are hosting a number of special events in selected stores in the UK and stateside, starting from March.  Avid Topshop fans will be able to enjoy complimentary prom inspired hair styling, makeovers and manicures. So we've rounded up some of Topshop's hottest prom style dresses to get you inspired - check out the gallery above.
