We know first-hand that most parents don't have the time or energy to make their own costumes for their little ones these days – personally, our nimble fingers are far more familiar darting across a smartphone that weaving a needle and thread.
But shop bought costumes can get expensive, and ordering online can feel like a bit of a gamble (especially when there's a fancy dress prize at stake!).
So savvy shoppers and Potter lovers alike will be thrilled to learn that ASDA have just launched their own range of Hogwarts robes. And on top of their trademarked 'rolled back' prices, the absolute best thing about the costumes is that they come in adults sizes too!
On this most spooky of holidays you can dress up as Minerva McGonagall or Albus Dumbledore, and your little ones are sorted with Gryffindor or Slytherin robes (complete with wand and glasses, if you're going all out Harry).
'Your transfiguration skills may not be up to scratch, but thanks to this costume you can still transform yourself into Professor McGonagall, the stern yet fair head of Gryffindor house,' says one magical description on the product.
'The full length cloak replicates the look of her green robes with intricate printed detail and the feathered pointed hat bears the Hogwarts crest for added authenticity. You won't even need a magic wand to win best dressed at your next fancy dress party (though if you do get one, remember its dragon heartstring, 9 ½ inches and made from the wood of a fir tree).'
The manufactures have clearly made sure that no expense has been spared, doing their research into exactly what Harry and the gang would have worn.
'Have they been sorted into Gryffindor?' says another. 'If so, this costume is the best way for them to emulate the house's most famous alumnus - Harry Potter.'
'The robes have been emblazoned with the lion coat of arms and feature the iconic pointed hood that everyone loves. Also included are a scarf in the Gryffindor colours, a pair of round glasses (wrap with sticky tape for maximum authenticity) and, most important of all, a wand.'
Prices range from £14 to £22 and the range is likely to sell out fast, so you might want to think about bringing the weekly shop forward a day or two...
