Looking for DIY ideas? 

Left it to the last-minute and need a DIY option? There are plenty of costumes you can create using things you already have in the home!

Where's Wally?

All you need for this look is a pair of unwanted glasses, a red and white striped top, a bobble hat (ideally in white) and a pair of blue trousers or jeans. Kids could even wear a blue or denim skirt if you have white and red stripped tights. 

Chimney Sweep 

Find some dull clothes from the small bag that you no longer want and start distressing them by making them look out of shape, ripped and dirty.

Brown, grey and black clothes work best for chimney sweep costumes and you could look like an extra from Oliver Twist or Mary Poppins! Use spots of black or brown powder make up on the face to create the soot effect and add a baker boy hat to complete the look. You could even find a prop that resembles a sweep! 

Mildred Hubble

Got a witches hat somewhere that you often pull out for Halloween? Use it to recreate the look of Mildred Hubble from the popular book series, The Worst Witch. Find a grey school pinafore, black tights, white school shirt, stripy tie and pull over a DIY black cape and your little one will look fit to attend Miss Cackle's Acadamy for Witches in no time. 

Mr Bump

We've all got bandages from the first aid box in the house! Recreate the look of the iconic Mr Bump from the Mr Men series by dressing up your child in a blue outfit before wrapping up their head and midriff with bandages! 

Queen of Hearts

You'll need a pack of cards for this costume! Find a black or red dress in your childs wardrobe - ideally one that they may not wear again and start to stick the heart cards onto the dress. You could even make a funky collar for the dress out of the cards! If you have a bit more time to spare, you could even stitch some hearts onto the dress too. For the crown, use any playing cards or even better some shiny gold card if you have any. Complete the look by taking inspiration from Helena Bonham-Carter's Queen of Hearts make-up from the 2010 Alice in Wonderland film with lipstick shaped as a heart and bright blue eyeshadow!
