Today ASOS and MasterCard are serving up a big, fat slice of sun-drenched happiness by launching what promises to be your best summer ever. Yes, even better than that one with the missing weekend, the mystery selfies and the unexplainable bruises.

This is truly going to be a season to remember… one filled with good weather (um, fingers crossed), good times and, of course, plenty of serious style. Best of all, we've lined up a whole stack of Priceless Surprises to make the next few months even more epic than they were going to be anyway.

To kick things off we’re offering two tickets to the Justin Timberlake show in Las Vegas. Not only will you get to experience the 20/20 EXPERIENCE WORLD TOUR first hand, we're throwing in travel, three night's stay at a four-star hotel and much more. Score.

To be in with a chance of getting your hands on this awesome prize, all you have to do is follow @ASOS, tag your favorite summer photos with #EpicSummer and we'll pick the best pics submitted. Before long, you could be watching the second most dapper man in the arena do his thing. Of course, we're assuming you're the first. 

Good luck you epic, epic winner, you!
