27 Cool Dressing Up Costumes For Kids

Fancy dress parties are go. These are the coolest costumes to fire little ones’ imaginations.

The summer holidays are approaching, which means one thing: no more school uniform for several weeks. And on June 21st, barring disaster, parties, whether indoor or outdoor, will be back on. Now is the moment, then, to make up for lost time and go mad with children’s fancy dress efforts. Those clever and creative enough will, of course, fashion their own costumes. But for the rest of us mere mortals, the good news is that excellent purveyors of dressing-up abound in the UK – with many so lovely that you wouldn’t mind if your child develops a devotion to said costume and refuses to take it off, ever again (not an unlikely outcome). Whether your little ones are into princesses or dinosaurs, fairies or pirates, these are the costumes we – and, more to the point, they – will love. Fancy times ahoy!
