Queen B would be proud.

Famous fashion favourites stepped out in an array of outfits this week, and we're here to break it all down for you.

It's official, headbands are back in style and it's all thanks to Kate Middleton.

The Duchess of Cambridge pulled a Blair Waldorf this week, donning a spotted headband while attending the Royal International Air Tattoo show with husband Prince William and son Prince George. Her recycled blue Stella McCartney dress and navy Smythe blazer matched the rest of the fam's ensembles perfectly.

Meanwhile, Catherine's sister, Pippa Middleton, kept her Wimbledon style game strong, sporting a printed '60s-print Tabitha Webb dress and giving us some major summer fashion inspo.
