The Mothercare Sale still has some great buys available, and these two dressing up costumes are hugely discounted. They were selling at £16 each, but are now right down to £5! You can't get any cheaper than that for a dressing up outfit!
There are two available at this price - a Snow Princess Costume and a Fire Fairy Outfit, though both could pass as lots of different characters with other accessories added.
Both outfits come in one size which is suitable for around 3 to 8 years. The wings are detachable on both outfits, which makes them even more versatile as they can be fairies as well as princesses.
Both have great reviews, and there's stock available for the free click and collect service or home delivery charges are from £3.95.
