Aldi is selling a range of Christmas Dress Up outfits for £3.99 each. You'll have to head in store to do so but they are rather cute. And while you're there, you can see if you can still pick up the Christmas books too - I managed to get all 6 yesterday.
It's not exactly Elsa, but at £3.99, the Ice Princess outfit is a fair addition to your Christmas fancy dress. There's also the always Christmassy pirate (that was sarcasm, although it could work in a panto.
The outfits I think will go pretty quickly are the boy Santa and miss Santa fancy dress. Especially at the price - just perfect for something that will only get a little bit of use over a few weeks.
