Choosing the ideal outfit for any wedding is challenging enough. So for these lot, finding the frock fit for an A-list occasion must have been a hair-tearing task. With wedding season upon us Team LBD have taken up the opportunity to check out who got it right and who got it really really damn wrong. Best dressed Kelly Osbourne at Kate Moss and Jamie Hince's wedding.

It was only inevitable that, for one of Britain’s top style icon’s big day, some serious show-stopping outfits would come out to play. A fine example? Kelly Osbourne. And in this figure pleasing gown Kelly has every reason to smile. Wedding guest gorgeous! Katherine Kelly at Zara Phillips and Mike Tindall’s wedding.

Hat's off to Katherine Kelly! The Corrie star swapped the street slacks for the day as she donned this particularly feminine blush coloured dress to Zara Phillips and Mike Tindall’s wedding last year. The outfit screams wow for all the right reasons. And here at Team LBD we love a good hat, especially this bold number by Jan Scott Russell.  Oh so boho. Kate Moss at Jade Jagger’s and Adrian Fillary's wedding

It’s never a surprise to see Kate Moss appear on the list of best dressed, but this time the party-loving model has gone for the classy and conservative look in Alexander McQueen. Wedding perfection we say. Pippa Middleton at Kate and Will's royal wedding

Of course we’ve saved a special place on our list for the picture-perfect Pippa. Without upstaging the bride, Pippa managed to carry off elegance with style. And while the Maid of Honour had the rest of the nation fixated on something else rather peachy, Team LBD had all eyes on that beautiful form fitting gown. Worst dressed  Princess Eugenie at Kate and Will’s royal wedding.

A good wedding hat is always a winner, but wearing one this daring to the most memorable wedding of our time isn’t the best idea. Sorry Princess, but we don’t think you’re living this one down for a while. We’re thinking more Alice in Wonderland than wedding.  Sarah Owen at Lily Allen and Sam Cooper's wedding

Lily Allen’s wedding was certainly one to remember after she chose her big day to announce that she was pregnant with her first child. But while Lily and Sam celebrated their double delight, there were two other prevalent things that stood out. Talk about a bizarre choice of outfit. Sorry Sarah, but it’s not your bumps we’re excited about. Tara Palmer Tomkinson at Kate and Will's royal wedding

Okay we get the whole royal blue thing but isn’t this a tad OTT? The socialite could cleverly have stopped at the chic Deborah Milner dress. Instead she added matching shoes, a matching clutch bag, a matching hat, matching elbow length gloves. We’re sure you could have borrowed an all-in-one if you'd really wanted Tara. Bianca and Mick Jagger at Jade Jagger and Adrian Fillary's wedding

These two definitely give a whole new meaning to embarrassing parents. In true wedding-Grinch fashion, Bianca donned a severe black suit while Mick looked more like he belonged in the chocolate factory. Poor Jade.
