This snugly Minnie Mouse outfit is described as a 'Walk In Sleeper' on the Mothercare website, but as it's not suitable for sleeping in then maybe a 'onesie' is more accurate (though less poetic). Either way this is a bargain as it was £16 originally and is now just £5, making it nearly 70% off.
This is an all-in-one, and it's fleecy and padded for extra warmth. It's an alternative to a dressing gown for keeping kiddies warm, but as already mentioned it is not suitable for overnight sleeping as children could overheat.
Although the picture shows 'feet' with a non-slip sole, from the customer reviews (which are really good) it seems that the larger sizes do not have feet and are more like a onesie, though it's hard to work out which sizes do have them.
This Minnie Mouse 'onesie' comes in sizes from 4 to 8 years, and at the moment all are in stock. You can click and collect from stores for free, or home delivery will cost from £3.95.
